(All remote due to COVID-19) Started with a screening call with the recruiter, then moved on to another with the hiring manager. After that, I was invited to two 4-hour meetings, where I was interviewed in 30-45 min increments. 12:30-4pm one day, 12:30-4pm the next day. I believe I interviewed with 8 total people. The last 45 minutes of day 2 consisted of a 20 minute presentation, followed by 10 minutes of Q&A from the entire panel of people that had been interviewing me.
