I applied through university. I interviewed at GammaStack (Bhopal) in Jul 2022
Interview
There were 4 rounds in total. First one was online coding assessment. After that there were three interviews round. All three was conducted on the same day. First Two was technical and last one was HR. In the first round they had asked for DSA and about the projects and in the second round again DSA and DBMS. Third round was managerial round.
It means the review process goes step by step — first to L1 (initial reviewer), then to L2 (senior reviewer), and finally to HR for the final verification or approval before completion.
