Got contacted by a recruiter in December end and got my round 1 & 2 scheduled on the same day in first week of Jan 2022.
Round 1 : Easy question on stacks, with a few followups.
Round 2 : Easy question on graph including Dijkstra and some followup discussions. Interviewer was not very friendly and pointed out some really trivial things and gave feedbacks like " took hints to optimize the code" and all, which I feel was not right.
Got a call from recruiter after 2 weeks for Round 3 & 4.
Round 3 : Ad-hoc question using sets. Graph questions with followups. Couldn't code the second question completely however explained the logic.
Round 4: Nice question on binary search.

Recieved an email after 3 working days to submit my resume and transcripts. It has been more than 2 weeks since the last mail and I have not recieved any response to any of my emails after this. Seems like a reject.
