first round was an online assessment round consisiting of 3 sections to be completed in 1.5 hours, aptitiude, technical and coding and level of questions was medium, negative marking was there. 24 students shortlisted for interviews.
3 rounds of technical interviews were there:
1st round focussed on aptitiude, mathematics and thought pricess, similar to OA questions.
12 students proceeded to second round. This round focussed on dsa as well as puzzzles medium level. more focus is on your approach and thought process rather than code/solution, you must know how to calculate time complexity of your approach. I was asked questions on linked list and binary search tree, some others were asked on dp. 3-4 puzzles, available on gfg.
round 3: this was very hard round, focussed on hard puzzles and dsa. it was very difficult to crack. I did not do well in this round so given one more technical interview.
round 4: DP problem climbing stairs, different approaches of the same question followed by a puzzle(8 balls puzzle) and then questions on dbms like antileft join, sql queries, joins vs subqueries difference, and 1-2 oops questions.
I could not make it to the final HR round
