December 1, 2023Company uses CoderPad test to haze candidates
Sounds bad, but it could be an honest mistake. I was asked to do a test for a Python/Go/AWS job. The Python section was hilariously easy, then the Go was some fiendishly tricky LeetCode thing, where you're basically screwed if you don't know the trick. And then rapid-fire multi-choice about obscure AWS services. Anyway, I emailed to complain, and apparently they asked the team to take the test themselves. The hiring manager apologised, and I took the job; ended up getting promoted to lead developer. More on reddit.com

r/embedded on Reddit: has anyone taken a CoderPad technical assessment?
December 1, 2023 -
I have a degree in ECE but I haven't written any code in about 4 years. I have an exam for an embedded systems role I applied for, but it doesn't have any rules listed.
Would I typically be allowed to google things during this test? That's pretty much how I've always coded because I always get syntax and functions mixed up between languages. I definitely couldn't answer the sample question without googling C documentation.

Is this a takehome thing completed at your own convenience or a live interview? If it's a takehome then Google is usually allowed (or at least not possible to restrict). Although be aware they usually make the time insufficient to constantly be using Google like that. If it's a live interview there will be no access to external sources. That's pretty much how I've always coded because I always get syntax and functions mixed up between languages. Is this just lack of effort into learning C or do you generally have difficulty getting syntax and function names correct? If it's dyslexia or something there are some pretty reasonable requests you can make like having a C cheat sheet in front of you, I think most interviewers would allow that. Open Google usage won't be considered reasonable, though.

r/recruitinghell on Reddit: Company uses CoderPad test to haze candidates
March 29, 2024 -
A company I applied to made me do a CoderPad test. The whole thing was nothing but esoterica about various languages. Stuff actual engineers rarely deal with and when they do they look it up in the docs. Stuff like “What’s the second parameter to API function X?” “Which of call() or apply() take an array for parameters?”, “What’s it called when you mix asynchronous and synchronous functions”?, shit like that. It was an hour test of nothing but that for Java, Node, GoLang and C++. I totally failed even though I have well over 10 years of experience with each, building real stuff.
Anyway… I thought it was over. I got the results back and I failed hard on every part. I was pissed that I wasted my time on rote learning bullshit likely put together by some Indian engineer who’s used to that shit No! The company was “impressed” and wants to schedule panel interviews. WTF?
Clearly it’s some hazing thing and I told the company to fuck off…

That’s why I no longer do Microsoft certifications. It’s more about language esoterica and your ability to memorize an api. The tests don’t seem to measure real-world ability. I have taken coder pad tests and I’ve administered plenty of them. I used to feel terrible because my company would task me to interview data science candidates, and I had to present them with a coder pad interview. Many would tell me that they haven’t coded in over a decade. It sucked, I was obligated to fail them because our company expected everybody to be able to code. I was forced to pass on experience data scientists for this reason.
