It was supposed to be 1 hour but it went till 2hours. And so far I had very bad experience while giving the interview... Because the interview was asking so much generic questions as it wasn't on point and his feedback was I was responding answer slow.. and If I was responding slow.. the most weird feedback ever. I think we should have allowed to think when someone is asking questions there is asking it from anywhere and we are one who has to think. On that I had the another last round interview that was got cancelled as it was stretched so long... But I never meet an interviewer who can't decide whether they want a candidate or not in next 15 or 20 mins even after 2 hours the feedback was you were slow answer giving and thats why you are on hold.

Would say the interviewer was a newbie and had to explain him few concepts. Would not recommend if they are saying they will record interview then only apply to this company.
