The interview process included an intro call, a Hackerrank assessment, two separate 1-hour deep dive coding sessions, and concluded with a final onsite interview that lasted approximately four to six hours.

They really hype up their interview process trying to make it sound like it's so different. Stating that they don't treat it as a screening or test-- that they try work the interview around the candidate. That's absolutely false... They just asked a leetcode problem and watch you solve it just like any other tech company has been doing.
