I fill out a form which just gives Intel your background information (name, address, citizenship, etc.) and what type of work you want (intern, full-time, location, time, etc.). In addition, I also submitted a resume. Both the form and the resume were submitted to HR. After that, I waited for any interested manager to contact me by email or phone. The initial contact is to establish the time for the phone interview.
During the phone interview, he asked some basic technical questions relating to C/C++, logic design, transistor circuits, etc. The challenge for me was remembering all the concepts. Other than that, the interview should not have been that difficult since he did not expect me to solve a problem.
The phone interview was around 30 mins to 45 mins long.
