The HR contacted me and provided all the details about the job. They then set up an interview schedule at the office.

There were five rounds of technical interviews, followed by a discussion with the manager. I was given the offer right at the end of that discussion.

All documentation was finished the same day. The entire process was extremely smooth and easy. Everyone was very professional and helpful throughout.

Questions related to complex algorithms.

Internals of the compiler and operating systems.

Cyber security related questions.
