I was rejected by Google after the on-site interview. I'm almost sure I didn't do great in only one out of all the 5 interviews. Is my judgement plain wrong or is one insufficient interview enough to be rejected? I interviewed with Google one year ago but I didn't end up getting the offer (for software developer). Recently a recruiter contacted me and positively said he would give me another interview. I wrote back after a day but didn't hear back. What is some advice?
