The initial stage involves an online HackerRank test, spanning two hours. It is crucial to remain on the test page throughout this duration, as switching browser tabs is prohibited and will trigger a warning from the HackerRank. The assessment comprises 30 questions covering a variety of topics, including operating systems (e.g., the banker's algorithm, threads, CPU scheduling), programming in C (e.g., structures, unions, strings), security, and several coding problems.

It was a very good interview experience. They asked a lot about my technical skills, including concepts related to my field, problem-solving ability, and past projects. They also focused on my communication skills, teamwork experience, and how I handle challenges in real-world scenarios.
