Very painless, phone screen from HR and then in person interview shortly after. Met with multiple people due to being from out of town, and was offered the job shortly after.

It was very relaxed and informative. There was an initial phone screen with the recruiter, which provided me with details on the next steps and gave me a great insight into the company's culture. I had a professional and behavioural interview with both peer level and management level interviewers. Final interview was with a Principal of the company.
