There was about 12 interview. 4 phone interview and then 8 on site interview with different kind of people. About half of them was technical with detail specific problem solution programming shell and operating system knowledge etc. The technical interview was very deep and good environment. The other half was manager interviews different problem solution and daily job situations one of them was through conference call to California. Each interview was about 45-60 minutes. In case of the manger interview sometimes it was very difficult to find out the real question and what they are would like to know what is the real test and what kind of solution they are looking for (even after the interview).
