I applied through a recruiter. The process took 1+ week. I interviewed at Wistron (Rolling Meadows, IL) in Mar 2014
Interview
2 phone interviews and a face-to-face. 1st phone interview was general background information, the second tested working knowledge of LTE. The face-to-face had some questions regarding both previous topics, but not as in depth. It was more to see if you could get along with the team at this point. Offer was made at the end.
