There were 3 rounds first one is hr which is quite simple, second one is aptitude -pen paper, 3rd was in google office again that was easy. they will mainly ask you about yourself , about your college project , and about knowledge graph.

I got four calls on different days, 2 calls from talent acquisition persons, then 3rd call from Manager and final 4th call from Hr. Questions they ask : (1) About yourself (2) Any idea about job role (3) Why you want do this job( If you are from different branch)
