Python interview questions I can use in interviews

Try and model the interview around what they will actually do on the job. Write algorithms Build an API (Flask, SQLAlchemy, FastAPI, SQL) / tests Integrate AI into an existing API Deploy web apps / Containerisation All of it (Take home test?) Then design your questions around that to be more representative. If someone is not going to be writing high-performance algorithms it's less fruitful to ask them to answer such questions in the interview. That said, basic knowledge of Python data structures and when to use Lists, Maps, Sets, Dicts, etc, should be tested along with good practices like Type Hinting, Logging, OOP, Unit Testing, SOLID principles etc. More on reddit.com

10 Python Interview Questions You need to know

I didn't know the first one. I wouldn't say it's something you need to know. Would be suprised to see it in an interview. It's rather obscure and if you need to do this then you are probably doing something wrong. Also I might have gone with

super(B, obj).show()

The others are pretty useful though.

For example, you might use an assert statement to check that a list is sorted before performing a binary search on the list. It’s important to note that the assert statement is used for debugging purposes and is not intended to be used as a way to handle runtime errors. In production code, you should use try and except blocks to handle exceptions that might be raised at runtime. Ans. In Python, decorators are a way to modify or extend the functionality of a function, method, or class without changing their source code.

r/learnpython on Reddit: Python interview questions I can use in interviews

September 19, 2024 -

Recently my workplace has started hiring python developers and since I'm one of the python guy I am asked to take python interviews starting today.

Now in my 4-5 years of learning and working with python I have accumulated a lot python challenges in my head as I'd constantly trying to come up questions that an interviewer might ask me.

Yesterday I made some samples questions and share with my senior who found the questions little too deep for a 3 YOE Python full stack developer role.

Please give me few questions to get some idea that I can use or be inspired from to make new set of questions.

Also is this question really too much for such interview: Given a file containing very large string (around a gb), devise an optimal solution to get the first non repeating Character.

Try and model the interview around what they will actually do on the job. Write algorithms Build an API (Flask, SQLAlchemy, FastAPI, SQL) / tests Integrate AI into an existing API Deploy web apps / Containerisation All of it (Take home test?) Then design your questions around that to be more representative. If someone is not going to be writing high-performance algorithms it's less fruitful to ask them to answer such questions in the interview. That said, basic knowledge of Python data structures and when to use Lists, Maps, Sets, Dicts, etc, should be tested along with good practices like Type Hinting, Logging, OOP, Unit Testing, SOLID principles etc.

Start with what the purpose of the interview is. What are you trying to evaluate? Does your interview question evaluate that?

Python coding test problem for interviews - Stack Overflow

I've asked candidates to write code to implement bowling scoring before, which is readily comprehensible but contains enough wrinkles that most people have to iterate their approach a couple times to cover all the edge cases.

A lot of the problems at http://www.streamtech.nl/site/problem+set, which are taken from ACM competitions, are also suitable for your use. I used them to familiarize myself with python syntax and language features. A lot amount to straightforward application of standard data structures; some are more focused on algorithmic issues. If you sort through them I'm sure you'll find several that fit your needs.
