I applied online. The process took 1 day. I interviewed at Intel Corporation (Hudson, MA) in Mar 2011
Interview
Interviewed with 6 different people for about an hour each. They all had they're own set of questions mostly programming in c++ and some basic digital design type question. Overall the process took about 7 hours. I recommend brushing up on basic c++ programming and finite state machine design.
The process took 2 days. I interviewed at Intel Corporation in Oct 2010
Interview
Met a recruiter at a campus career fair and was invited to an interview the following morning. The interview lasted about 45 minutes and consisted primarily of technical questions ranging from transistors to C programming. A week later, I was invited to come onsite for 2nd round interviews. The interviews lasted all morning and consisted of 4 40-minute interviews consecutively, all of which were technical. The interviews were followed by lunch with the interviewers and then a tour of the testing facilities.
