I had three onsite interviews, which were easy to medium in difficulty. The interviewers did not seem very well prepared, but everyone was generally friendly and competent.

However, HR is a mess. It took them over three months from the day of my onsite interview to send me an actual offer letter, which is completely unacceptable. Furthermore, they did not communicate with me at all; they would tell me they would get back to me that week and then not respond for another two to three weeks. And you can bet they won't reimburse you for your onsite interview.

I had a good onsite interview experience and might have even considered Yahoo had their recruiting team not been so awful. It really reflects badly on the rest of the company.

Coding question before the interviews started on your own personal computer.

Can't share, however, because of NDA.
