I did a 1 hour tech screen with an engineer and then moved onto the on-site. The on-site consisted of 4 sessions, each about 1 hour. There was one technical question, one system design question, one behavioral interview with an engineer, one behavioral interview with someone from the product team. The interview process was great, everyone I talked to was very nice and helped to remove the stress that is inherent in this process. They were very quick on turnaround and keeping the process moving. Once they had made me an offer they were very clear about showing their interest and desire to have me join, including setting up a virtual happy hour to meet more of the team. This is a place where people both feel a passion for what they are working on and really like the people they are working with.
