Standard interview. First and second were conducted by phone. Flown in for 3rd. The second interview was conducted by peer-equivalents. Third interview was with managers that lasted for a few hours in an afternoon, and meeting the rest of the staff.

I applied six months earlier through an employee referral and they seemed interested but had no availability. They reached out about the same position later, at which point I was ready to leave my job. The interview was very quick, friendly, and colloquial. Only had one interview before getting an offer. I met the team manager who then brought two other team members to meet me. They described the position concisely. They were ready to bring me on quickly and the interview only took about 15 minutes.
