The first round is a simple phone screen. Then you will be asked to block off 2 hours for multiple interviews. The hiring manager will take note of your performance during the first interview and then you'll get a call back asap to see if you advance to the next.

Got reached out to by a recruiter. Passed the screening call last week. rd1 interview is coming up this week (11 days after). Apparently only 2 rds of interviews this process. Though the 2nd interview consists of 2 45min interviews in one.
