A data scientist’s daily work usually includes cleaning and analyzing data, building models, and turning results into useful insights. Some tasks overlap with AI tools, but most of the job is about finding patterns in data and explaining them clearly, not building complex systems like neural networks or NLP models from scratch. If you want to go deeper into AI or machine learning, starting with the basics is really important. A structured course like this article explains the fundamentals step by step, with hands-on exercises that help build a strong foundation before moving into areas like computer vision or NLP.

r/datascience on Reddit: What do data scientists actually do on their day-to-day?
April 12, 2019 -

I know they code and use statistical models on huge amounts of data to come to conclusions or train the models even more but what do they ACTUALLY do? What do they spend most of their time doing? What do they rarely do?

I'm thinking of getting a master's at DS but I'm overwhelmed by the amount of tasks "data science" includes and I'm trying to figure out what the day-to-day of a data scientist looks like and how would that interest me.

Drinking coffee, checking reddit and stackoverflow, being in meetings. Joking aside, there is a flaw with your question, and that is that you assume that all data scientists do the same tasks, or have even moderately similar day-to-days. Put differently: you just asked the equivalent of "what do lawyers actually do in their day to day?" I imagine that your day to day looks very different if you're a litigator vs. an IP attorney, vs. an international tax law attorney vs. a forensic attorney vs. a constitutional law attorney. The same is true for data science, but with maybe even looser boundaries. To oversimplify the world, I would say there are going to be 4 types of tasks that data scientists do on some regular cadence: Research: you will have to read up on different ways to solve problems, or different tools/technologies that you can use, or how to tackle specific modeling issues, or how to call a function, etc. It can be as quick as a 5 minute read on a new package in Python, or as long as several weeks to do a comprehensive literature review on modeling methods. Code: once you somewhat know what you have to do, you have do it. Normally you will start by identifying the data that you will need, scoping it, examining it, cleaning it, looking at it some more, do some basic analysis on it, clean it some more, do more advanced analysis, clean it again, put it in a nice format for modeling, more cleaning, and then code up some type of model. Then you clean the data some more, tune your model, debug it, clean, tune, debug, debug debug debug debug debug debug, look at results, they don't make sense, debug debug debug debug debug debug, hey that looks like something that makes sense, oh wait, no, debug debug debug, ok, that looks reasonable. Communicate results: you now have results and you need to convince someone in the organization that those results are good, and that those results are useful. Discuss how to make data science work usable by the organization: once you are able to convince key people that your work is useful, you will need to work with other people across the organization to execute your work in a way that actually drives better outputs. Your usual suspects will be your enterprise development team, a project manager/management team, and the lead business unit responsible for the process that you are working on improving.

Besides modeling, there’s a lot of cleaning, merging, training, parsing, visualization and other prep work for big datasets. Then there’s a lot of admin work, meetings and stuff really eat into my time at work.

I’m really curious to understand the day-to-day life of a data scientist. They work with data, but what does that actually look like in practice? Specifically, I’m wondering how much of their work is focused on AI technologies.

Do data scientists work directly with advanced fields like AI, computer vision, natural language processing (NLP), and neural networks? For example, if I want to learn more about these areas, should I pursue a career as a machine learning engineer or is there room for that within the data scientist role as well?

In general: is it a great role to gain AI expertise to maybe found a startup one day or not so much?

Hey guys, just trying to understand better some topics that I heard about data science.

I was told that a typical day in a data scientist job was:

1 - Planning (sprint etc)

2 - Data aggregation/manipulation/cleaning/querying

3 - Data Analysis (basicly find patterns in the data and prepare some visualizations of it)

4 - Model Building

5 - Model Implementation

Would you guys add any other specific task? Also, can anyone clarify to me what topics 4 and 5 would be? I imagine it as preparing algorithms to collect more data or calculations for new entries in the database, testing them, etc..

Thanks!

I have 8 YOE, from what I've seen there are a few different subtypes of data science jobs "analyst" data scientist - pretty much just writes sql queries and does data engineering, doesn't really use "AI" to solve business problems because it isn't necessary "modeler" data scientist - data is usually prepped and ready to rock, they click "train model" and hang out while it trains (my favorite) then monitor and respond to model drift. Might be more devops heavy too "communications" data scientist - they spend about 10% of their time doing actual data science and the other 90% in meetings and making slide decks and presentations I've done all 3 at different companies, some hybrid and some remote - the business determines what type you are. I think the best place to be a data scientist is at tech companies because you're more likely to be a "modeler" due to the advanced engineering culture. Huge banks and legacy companies are usually "communications" with some "analysts" (given the caveat that huge companies can have "modelers" but they usually lag behind in their tech stack and engineering culture). YMMV

Applied data scientist here with 10 yoe in a large tech company. Most of the time I am just making sure data pipelines don't break and migrating from system A to system B. Probably 30% of the time engaging stakeholders to build trust and make sure they don't do stupid shit. 10% of the time managing my boss, his boss, his boss' boss,... ... so they stay grounded in reality and not in a fantasy world where LLM can replace human , and probably 10 % of the time building, modeling, automating stuff.

Hey pp, just wondering what do you do daily and what models do you use to solve your problems! What is the complexity of such work? I am thinking about switching to a DS role to be more interactive with the data and able to answer questions

I am an ML Engineer (or SWE working in ML domain), whose work is mostly on pipelines and infrastructures and only around 20% is spent on building models. I use big deep reinforcement learning models for my products but I guess it would not be used in DS space due to the black-box nature.

I wonder what would you use most often? How do you interpret and deliver it to others? Any other interesting tasks you do except for predictive modeling? If it is pure data cleaning and regression then I don't know how it differs from BI

Why would you want to be a data scientist if you’re already a MLE? In my experience DS usually pays less. My day to day varies a lot. Kinda depends on the project. I work in a marketing vertical so I build a lot of propensity models. Sometimes I use logistic regression but that’s usually just for stakeholders who force me to. I’ll usually use random forests, xgboost, lightGBM. When I’m doing customer segmentation I’ll use unsupervised algos like Kmeans/hierarchical clustering. I also do forecasting. All of this happens in python but previous jobs required me to use R or SAS. As far as delivering results, that’s also project dependent. For most projects it starts with a proof of concept model that I’ll then pitch to stakeholders. If they like it, I put it into production, meaning it can run on its own (could just be scoring or training and scoring) at a set schedule and populate results into a destination where others can use it. Sometimes that could just be a database table, a marketing tool, and occasionally it’s a dashboard. My company has a big data org so we have people who can build dashboards for us. When I worked in analytics, it was less modeling and more finding insights. I used a lot of Excel whereas in DS I might use Excel a few times a year. Usually just to make charts for PPTs if I think the python plots are too ugly. When I work with analytics people as a data scientist, they’re usually using my model to find insights. All of us use SQL though.

I'm considering data analysis as a career, largely because a) I'm pretty good with spreadsheets. b) I hear it pays well. c) I hear the job market is pretty good.

That said, I know nothing about SQL, Python (or any other programming language). I'm considering going back to school for this. I have a Bachelor's in Operations Management, which has some, but not many, parallel skills. My Bachelor's is also 15 years old and I don't honestly remember a ton of the information.

I'd like to know more about what data analysts actually do, without all the industry jargon. Any insight would be much appreciated.

I create picture books for fancy adults who wear suits. Much like a librarian people come to wanting know things about a subject. I must know enough about the subject to order the knowledge, figure out where to keep it, and be able to find it when it's asked for. It is my job to make sure adults have a great time using my department. That they are rarely overwhelmed or confused. So that part is kinda like customer service. Most of my efforts are spent making people trust me, so I have to spend less time making them trust my work. I also sit through a bazillion standups ( group check-ins) and meetings where we sort sticky notes on a board. ( This is called agile most analyst don't do this) I write code. I tidy warehouses and fill them. But most of all I make picture books for adults and keep them happy and not confused or scared.

If you're starting on ground zero, but have work experience , then look into "business analyst" instead. If you go for data analyst roles, you'll be competing with CS / MIS / IT graduates who are well versed in multiple programming languages since their teen years. Business analyst still need the technical skills like SQL/python/tableau or power bi /R, but they also need to be able to converse with internal teams and stakeholders. My brother is a software engineer and he says it's tough competing with internationals because while it's 'just a job' for him, it's literally 'life or death' for others because not securing a job is a one way ticket back to 3rd world poverty & dead end outlook. From my limited observations in my work setting, companies have no problem hiring the brightest minds for data analyst roles to ensure they're able to produce data. Meanwhile, business analyst have to effectively translate data to non technical stakeholders. I know my whole post is centered around race/origin. Ofc it doesn't apply everywhere and I have native US friends who are data analyst as well. But speaking in generality.

Please mention your job title and what you do everyday at work. Are you programming? Cleaning data? Running tests? Thinking of how to interpret data? In meetings?

I want to know how you spend your day so aspiring data workers can know what to expect. I recently spoke to graduates from a data science bootcamp and they said they spent most of their time cleaning data while working on their capstone projects. I hate to say this but cleaning data seems incredibly boring and dry, and I just want to know what you do at work so I, and others, can have a realistic idea of what we are working towards.

My job title is Data Scientist. A typical week for me is 40% coding/working on my specific projects. I’m only on one project right now that we estimate will be done in December, and I anticipate being added to another project next month to split my time on. I spend about 20% researching new technologies that we could utilize, 20% data collection / cleaning, 20% fucking around on the internet (jk the last 20% is spent in meetings). I just graduated and began my job a month ago, however I did 2 full time internships at the same company that I now work at so I am pretty comfortable in this workflow. I absolutely LOVE my job. It’s pretty much everything I could’ve dreamed of as a new grad.

There isn't really a typical day. I guess a lot of it is writing SQL queries to get data and there most of the problem is in knowing where the data I need is stored and how as our data isn't that well documented so it takes time to learn where it will be in the format most amenable to your specific use case etc. Other days I can be trying to re-implement the hash function used in the server-side in Python to check some test assignments or using a library to consume events directly from Kafka or writing a custom reducer to look at the historical time series of events a user had. I try to work almost always in Python as then I find it's less of a pain - sometimes working out how to manipulate the data in pandas can be a pain for certain pivot tables or like if you want to plot a grouped, stacked bar chart etc. I think the worst parts are when we have to make stuff in Excel to give to stakeholders or of course the dreaded powerpoint presentations. Some people really hate dashboarding but I made a whole suite of dashboards in Shiny in a previous role (I've moved between various departments) and I liked that work as it was genuinely helpful to a lot of people as opposed to spending ages making some slides that will be breezed over in 30 seconds and might not even make any difference. I've also done some modelling both with anomaly detection in time series and SVMs for text classification. I have studied ML at grad school so I like to get the opportunity to work on it and hopefully it'll be easier soon as we migrate to GCP so deploying models becomes a lot simpler. Generally the job is good - I just really hate making slides and doing stuff in Excel. I'm getting better at avoiding that though :P In general I much prefer working on our python libraries or dashboarding or building models versus doing one-off analyses as I feel the prior work is much more likely to be used multiple times so it feels like a better use of my time.

I am an analyst working in a research lab. Here is what my typical day is: 7:50- Get up, check internet, eat cereal 8:30- Catch the bus to work 8:50- Get into work, get settled for the day, start checking e-mails, read a little bit of Reddit for 15 minutes or so if it's not a busy day. If I'm the first one in the office, I'll play music while I start to work until someone else comes in. 9:30- Start working on any projects that I need to finish up. I usually start by doing the easiest thing if there is no priority project because I hate mornings and need to ease in. This could be preparing data files or working on some R/Python code or submitting jobs for analysis. Usually these projects have some sort of deadline 10:30- Eat part of my lunch at my desk because I can't wait until a normal time. 12:00- Most likely have finished up work from the morning. Eat the rest of my lunch at my desk while I'm reading e-mails and take a 5 minute internet break. 12:30- Start working on the harder long-term stuff. This is usually finding and cleaning data files or running summary statistics and making plots, etc. or working on longer scripts. 2:00- Have a project meeting, lab meeting, or conference call. 3:00- Start working on anything that was assigned during the meeting. This is usually modifying whatever I did in the morning. 4:30- Keep working until I get to a starting point or until I've finished up everything I've needed to get done. Post updates/methods from the projects on my online lab notebook. Even though we don't have to stay until 5:00 if we finish everything, I don't like to leave early so I will usually find a paper to read pertaining to something I'm working on. 5:05- Catch the bus home. Cook dinner/eat/think about doing something productive/waste time on the internet/check work e-mail to make sure there is nothing I need to do before tomorrow 12:00- Bed All in all, I really like my job. I work in a pretty laid back office, so I can set my own hours and work from home if I need to one day. Obviously it won't be this way everywhere, especially if you are in industry I would assume. The worst part of my job is if I overestimate or underestimate the amount of time I need to work on a project. Having too much to do is stressful, but I know that I can always take my work home if I need to. Having too little to do is worse. Like today I got everything done in about 4 hours but my boss was on vacation so I couldn't ask for any more work. I don't like to "waste time" at work, so I try to read papers or work on creating an R package or something, but the day really drags for me because it is not as stimulating when I am doing work on a project. A tough project is my favorite and least favorite part. Figuring out how to do something that no one else knows how to do or how to adapt a new software for your needs can be incredibly difficult but is very rewarding when you succeed. Sorry for the ramble, just my $0.02. Take into account that I am quite novice and under-qualified for my position so it may or may not be applicable.

I am an analyst for a marketing team at a startup, here is my day: 6:00am - Wake, Eat/Coffee 7:00am - Gym for my daily workout 8:11am - Bus to work 8:50am - Get into office, start planning the day and lining up my Trello board. I use Trello for prioritization and intake, so keeping it up to date and organized is very important. At this time I also plan what I will say at stand-up, which is where we individually present to the data team what our plan is for the day, what blockers we have, and what we accomplished the day before. 9:30am - Standup. 10:00am - Work until lunch. This is mostly SQL/Excel/Python/R. 12:00pm - Lunch. 1:00-5:00pm - The afternoon is typically filled with work and peppered with meetings. Then I go home. There are LOTS of meetings. As an analyst or data scientist it's my job to validate, to the best of my abilities, the claims that everyone is making. This means having me in lots of meetings, with anyone from interns to the CEO. I have 10X the amount of work on my plate than I have time to do. There are bugs in the data. The problems are hard. None of it's pretty. BUT, it's so fun. So, so fun. The people I work with are incredibly smart, the company is awesome, it's super rewarding, and only god knows why they let me on the team.

What do you like about being a data scientist? Data. Ever since I can remember I would make data sheets of anything. Data gives perspective that otherwise would be unknown. Ironically, sometimes I like spending 5+ hours just cleaning data because it's so mindless. I would literally just listen to music while on autopilot. What don't you like about being a data scientist? This may be just the company I work for but people LOVE to interrupt me. Does it ever feel like a grind/work? Not really, I love my job. The only time I feel less interested is when I work for uninteresting companies that don't appeal to me. Did you have another passion you regret not following? No. I have many passions but I don't regret it. Data Science is a great path with potential for the future. Even if I were to start a company, Data science is never wasted time.

I've been doing this for the past 9 years at startups, marketing agencies, a 140 year old company with heaps of messy data, and now at the company with the most payment data in the world(think 90-100pb of clean mastered data). at the base of it, most data scientists are hired for business analytical reporting with sql, python, PowerPoint, excel, and tableau/powerbi. Executives use the insights from your work to guide and back their decisions. There's a wide range of use cases both external and internal such as HR data. It pays well but you'll hit a ceiling both in pay and the value you can offer, because to go further it is business domain knowledge and people management skills that are the differentiators. Like most things in tech, be prepared to learn and relearn every few years on new skills and toolsets - sometimes to accomplish the same tasks. Hope this helps, cheers.
