Google Technical Recruiter interview questions

Long interview process, hiring based on GPA and job performance. Phone interviews can be 1-3. Onsite interview one round of 4 interviews, can be 30-45 min. Once hiring manager gives thumbs up recruiter has to complete a packet to justify hiring. Two formal review committes to respond to. All hiring is done through committee. Hiring manager has no recourse.

After a long process I was finally called in for a face to face interview which was interesting, thought provoking. I enjoyed the interview and was told that it went well and should hear from them within2 weeks. Got further positive feedback from the consultant who had originally set up the interview and about 3 wks later and email saying I was unsuccessful... I would have appreciated a bit of constructive feedback.
