Started with a 30-minute phone interview, then a week later an on-site interview. There were two parts to the interview: first, a written test, then four people interviewed me with technical and situational questions. The on-site written test is fair

1. Online assessment covering network, operating system, and Linux. This includes approximately 10 multiple-choice questions and 2 or 3 coding questions about data structures and API design. Some coding questions require specific programming language

Three interviewers interviewed me. They were kind and rigorous. I was asked some questions about C++, networks, and operating systems. No coding exercise during the interview. They focused on the description and the projects listed on your resume.
