3. Multiple Technical Round

This round has multiple segments. First is Technical Round 1 and second is Technical Round 2.

Technical Round 1- This a face-to-face algorithmic round, in which candidates are given 3-4 questions based on only data structures.

Technical Round 2- Same as round 1 but with more intensity and difficulty. Candidates have to have a clear knowledge of data structures and algorithms.

4. The Hiring Manager Round
