Google

I was interviewed over the phone and wrote code in a shared Google Document. The questions weren't overly difficult, and the interviewer was excellent at guiding the direction of the code without telling me what to do explicitly. They decided to fly

Really disorganized phone call. The recruiter gathered information, including programming language of choice. The interviewer said he wasn't familiar with the programming language, then made me complete the interview using a language I'm less comfort

This is a standard tech interview. Many books out there can walk you through it. It typically involves a phone screen followed by four rounds of on-site interviews. This is normal.
