It was a waste of time for myself. - First, 5 mins of HR interview. The interviewer was did not pay enough attention during the interview. - Next step, they send my application to the technical people. - Next step was a take home assignment. - The requirements were heavy, it took like 16 hours of work to complete it. (despite the fact that they told it would take 2-3 hours) - I submitted the assignment with proper documentation about the design. - I got rejected without any feedback. - I emailed them asking for feedback. Somebody answered but apparently they were not capable of understanding the solution I provided even with the documentation I provided. Their feedback was totally nonsense. I provided a feedback to them that they need to be clear about the requirements, expectation from the challenge and the estimated time of work for the task. I hope they listen and change their attitude.
