Applied through the career's portal, a month later I was contacted by the recruiter regarding the interview procedure.
Will try to share my interview experience, cannot specify the exact questions but will state the topic and difficulty.

Phone Screening (45 mins) - LH

Was asked a N-ary tree question, could be solved using DFS. Would rate it medium/hard.
Solved the main problem, then discussed an approach for the follow up but did not have the time to code it.
Was informed by the reruiter that the phone screening was positive in a couple of days, and then scheduled the onsite interview rounds.
The recruiter let me specify my time slots which was really helpful as I'm currently working and could schedule the interviews as per my convenience.

Technical Round 1 (45 mins) - LH

Was asked a three part graph question, could be solved using DFS.
Solved all the parts, but was not not able to come up with an optimized solution for the last part.
Would rate this problem medium/hard.

Technical round 2 (45 mins) - SH

Was asked a very interesting and unique graph problem.
Spent the first 35 minutes discussing the problem and approaches, came to the conlusion that the problem can be solved using Union Find.
Quickly wrote the code after. The interview was very engaging, was the best interview experience I've had till date.
Would rate this problem hard.

Technical round 3 (45 min) - H

Was asked a sliding window question. (Was so happy realizing this!!)
Would rate this problem medium.

Googleyness round (45 mins) - H

Standard behavioural and situational questions.

Ten days after the completion of the onsites was contacted by the recruiter that the rounds were positive and we will be proceeding to the next steps. Currently at team matching since a few days.

Will be updating this post as we go along.
