Glassdoor Software Engineering interview questions

The interviewer sounds sleepy and tired, every time I finished my talk I need 3 secs to get the response. He finished my interview in about 15 mins and let me ask questions. Anyway, as a company for users to evaluate company and prepare interviews, I expected glassdoor to have a more professional interview. Update: Actually I got the second round interview, maybe my interviewer is just tired, or there is some signal problem. Another Update: The interviewer of second round interview is really nice. And I got the final round interview. But I just have no time to finish it. The overall interview experience is pretty good.
