Wait at the front for interviewer to come welcome you. Interview with the first person for 15 minutes and another person afterwards for about the same amount of time. A brief writing sample at the end. They give you a tour of the office space.

I met with 3 people. First the team manager and a recruiter for the initial "tell me about yourself" questions. We talked for maybe 20-30 minutes. I then got a tour of the office and had a writing prompt. Afterwards I talked to the team manager again for a few minutes then met with another manager. It felt like it went by fast because I was getting along with the interviewers so well! I got a call about 15 minutes after leaving the office with the job offer!
