I applied through a recruiter. The interview was online, but I wasn't told what the discussion would be about. On calling the HR, she said it would be around big data, but on the call, the problem we discussed was on normal system design. The interviewer was nice, and we had a pretty good discussion on it.

However, it has been more than a week, and there is yet no word or email from them on the feedback or the reason for the rejection. Not to sound disgruntled, I have heard a lot of good stuff about what the company is doing in terms of work, but it is letting itself down in terms of having basic conduct ethics when hiring personnel.

There was a system design question on how to design recurring events for the shipping service.
