As a manager, I had to take the coding test and failed it.
Important thing about their coding test — it is extremely unprofessional.
1/ They tell you that the test is timed. That is a lie. Every question is timed, from 15 seconds to 10 minutes.
Yes. 15 seconds to answer some multiple choice question.
2/ For ALL questions, the time is inadequately insufficient. 10 minutes to write a function with dynamic programming, sorting and matching.
3/ They lower your scores on purpose. For example, they gave me 30% score on Python (right?) when I answered at least 80% of the questions,
4/ The entire coding test was completely irrelevant to the Management title and to the subject domain (AI)
5/ College-level questions, such as "what is the default value of the parameter X in function Y in the package Z. Don't use Google". Right?
All in all, completely unprofessional setting, feels like a card game with a cheat. Stay away from them… they probably do the same if they hire you...
