There were 3 technical rounds.
Round 1: Started with a puzzle-solving (similar to one found in GFG or interviewBit puzzles section). Then DS questions were asked(mainly arrays). Questions from the work done in current org. . Python language-related questions as I had mainly worked with Python in my current organization. Resume projects were also discussed in brief.
Round 2: Mainly focuses on DS/Algo. Again the favorite go-to topic is arrays. This time questions were trickier than the previous round, with 2-D array sorting questions, etc.
Round 3: This round was taken by the hiring manager, he asked about my projects in my current organization, asked some software designing and architectural situational questions. Asked me about the most challenging project I have worked on.
