After the interview there is a take home exam. They said that the exam will only take 4 hours to complete. But it took my whole day to finished it. It was a bad experience for me because i didn't learn anything in the process. The interviewer just said 'you didn't meet the minimum score' its not a multiple choice exam so at least they could have explained more why the application will not move forward. I guess i just want some feedback since i invested my time to do the exam.
