Started with an online proctored hackerrank. There was no recruiter in the loop, only a hiring manager. They reached out after 4 months after applying. The next round was a 30 minute hiring manager call, which they explicitly tell you not to prep for and it's just to learn about the company and team, but mine ended up being a very specific behavioral interview and a technical deep dive. They ghosted me with no update even after following up, but the final round would've been a 3 hour technical interview.
