BlackRock Software Developer interview questions

Had 3 rounds, 2 of which were technical and 1 hr round. The 1stround was of around 60min. The questions were mostly dsa based, sql and projects were asked. The 2nd round was based on system design.

It was an online interview for on-campus placements which included 1 or 2 tech rounds (based on how you answer) and also a HR round . Tech round consists of some DSA questions ( Linked list implementation from scratch in my case ) and some basic theory questions.
