There were three rounds: two technical and one managerial.

As I had approximately 4.7 years of experience in LTE NW protocol layer 2 and layer 3, my interviewer started with logical puzzles like the egg drop puzzle and the finding average salary puzzle.

The next round was conducted by a technical lead. She asked many questions about my previous projects, the challenges I faced while working on different projects, and the approaches I took to resolve issues.

The third round was a discussion with the manager. It started with a brief introduction, then focused on achievements and college academic projects. He presented an image processing problem and asked how I would represent the image in programming and then create a mirror image of it. I was asked to write the logic for it.

He wanted to see how I could formalize the requirements.
