A phone interview was scheduled with me via email. Unfortunately, the interviewer never called. Even after contacting the person several, I received no response or explanation as to why. I found this to be very unprofessional and inconsiderate.

There were 3 interviews for the first round, followed by 3 more in a second round. Typically the first was one on one, the second with a group, and the third another one on one. Very friendly interview, not too challenging. In my interview I had some brain teasers, which were hard, but I got through them ok.
