I've attended many interviews, and this time the interviewer expected me to guess the question. They didn't explain it properly or completely, yet still expected me to solve the problem they had in mind. Even if you're capable of solving it, interviewers like these make it unnecessarily difficult to secure a job.

Good interview, with many real-time questions. Very interesting set of questions, all practical. Overall very pleasant experience. I had three rounds, one was with a manager, second was technical online interview and thrid was a face to face interview.
