Generally 2 rounds but i had to go through 3 rounds
First - general intro, guesstimate and case interview
Second - more deep dive intro your profile, and again guesstimate and case interview, this is more unpredictable
Third - they said it would be culture fit round, but it again went on your profile to see if your resume and story hold up then anything can be asked here, i was asked random SQL & excel question as well.
