1 phone screen followed by 2 onsite interviews. They expect medium level leetcode questions to be solved and coded in < 10 minutes. I thought I did well but did not get an offer

Submitted a resume online and heard from a recruiter within 2 business days wanting to setup an initial call. That ended up not happening and instead I was scheduled for a technical phone screen which had 3 phases: (1) programming question (basic) (2) past projects (3) brainstorm I wasn't properly prepared as I had not expected such a fast turn-around so I would say did poorly overall and wasn't surprised to not get brought back in. Process typically involves an on-site, then meeting the CEO and then offer and apparently normally takes 2-3 weeks depending primarily on scheduling. They move fast!
