They gave me homework task to solve it within 2 hours, I implemented task. After 4 days they answered me very strange feedback. Their feedback is not adequate.Especially following sentence is so stupid: "focused on performance rather than readability of the code" - First of all 2 hours is not enough for readibility, focused on proper implementation (I think code was quite readable) I have doubts regarding their expertise. They mentioned in feedback that I spent time on multi-threading. Because multi-threading is important factor for processing.In our case log processing. I really disappointed spending time on their task. I wouldn't want to join this unprofessional company in future where they see tests as pros and they see my tests overcomplicated. I don't suggest you to waste time for them.
