I submitted my resume to one of the people at the career fair. Talked to them briefly, and received an email that they would like to fly me to Tucson, Arizona for an interview. It was a pretty good hotel, and the whole process was great. Talked to many recruiters and people who worked at the company. The interview happened at the very end of the recruiting event, and entailed a lot of technical interview questions such as Op-Amp, BJTs, and MOSFETS.
