Initially contacted for phone interview. Followed by additional phone interview by Senior Recruiting representative. Two at location interviews within 2 weeks time -- interviewed by hiring manager and 4 additional members of management team, plus a lunch with potential team members. After the final interview, it was only a few days before I was contacted by HR about their decision. Process was pretty in-depth, but the time frame was quite fast. Only 3 weeks from initial contact to offer made.

Two rounds, one with multiple interviewers (second round). Felt like a conversation as it was somewhat relaxed. Mix between getting to know the company and my background along with technical questions
