The interviewers are friendly .After spending 5 hrs for interview you would expect a feedback.HRs do not respond at.I have read the glassdoor negative reviews still attended the interviews for the hype it has .All the reviews in glassdoor about the interview process are true.If you want to have a mock interview for interview experience this is the place, except that you don t get a feedback.Interviews are fairly easy.You will not understand why you are rejected.
