Initial communication was through a recruiter, who reached out unprompted via LinkedIn. After chatting with the recruiter briefly over the phone, she quickly set me up for a phone interview, which was not that difficult/unexpected. This was followed by a half-day on-site interview, which involved lunch followed by meeting with four separate employees four 45-60 minutes each. Interviews were back-to-back, and the last interviewer escorted me back to the lobby.
