About 45 minutes interview, all of the questions about a piece of code. I need to debug the code. The most challenge part is that all the bugs can not show in the result. If you run the code, the result is fine and no bugs reported. You need to find the bug with the result and the description beyond each method. I do not think it's a good way in interview if you test some details in code with a time limit. But, anyway, if you are a good programmer, you should handle all cases.

It was a very casual interview. I was told the interview would start at 8:45 AM but it started around 10 AM. The interviewer was very friendly and walked me through my thought process towards solving the given problem. There were two rounds of interviews, purely technical though I did not get shortlisted for the second round.
