One 1.5 hour interview (technical), one 1 hour interview (behavioral). This was after doing online assessment. Consisted of coding questions and brainteaser games. Also had behavioral test in the online assessment.
OA consisted of several games, usual optimization and car building game. The next round was standard technical with 2 interviews that are 45 minutes, leetcode style. The final round was a behavioral which is pretty standard.
