The application process starts with an HR screening. Followed by an interview with the HR. If successful, the HR forwards the CV to the hiring manager. If the hiring manager gives a go, a second interview is scheduled. In this interview, they mostly discuss your background and what you have done. They also ask questions regarding some of the projects you did and how you did them. If successful a third interview is scheduled. This one is technical. Expect code debugging in C++, computer vision questions like convolution, filtering, and some math problems.

Overall, the managers were very nice and respectful. The downside is that they take very long, and if you are rejected after 3 interviews, expect 2-3 months wasted.

Explain the Fourier transform, some OOP concepts in C++, some computer vision questions like erosion, ablation etc.
