Google

I was introduced to the company via email. The recruiter made sure I was up to date on data structures and algorithms before going any further. After this, the next phone interview was a casual phone call. The recruiter set up an application for me

The first phone call was the interviewer trying to see which position one would best fit. After this, an email was sent with the day of the actual coding question interview.

I had two back-to-back interviews at one of Google's offices. The first interviewer was awesome, but the second was very reluctant in answering questions I had about the parameters of the questions.
