First, a phone interview with basic knowledge questions. After passing the phone interview, I was called to a frontal interview. After passing the frontal interview, you should have an HR interview before you get hired.

First round was an online MCQ in which they asked aptitude, verbal, logical reasoning, debugging, and Linux. Second round: They asked about electronics engineering basics, computer networks, and two medium-level programming questions.

It was a 2-round process. The 1st round was technical, in which they gave two DSA questions which were medium level from Binary Tree and strings. They just want to know that the candidate is able to answer both the brute force and optimal solutions
