Google Software Engineer Manager interview questions

It started from the HR call. HR was very polite and friendly. Discussed how much time I need to prepare for the interview. After we agreed wit the date, there was a first technical interview where I had to show my knowledge in algorithms. After I passed this interview, HR called me with congratulations and scheduled for the next interviews. The second part was much difficult. It was the interview with 5 different persons 45-60 mins each. This part I failed. But even after that HR called me and discussed everything what was wrong and the reasons why I have not passed. In general, it was a nice impression about the HR work.
