Had a video interview (recorded myself) was easy to do and they give you unlimited time. The questions were non-technical. There were about 5-7 questions. Took me under an hour.
I applied through college or university. The process took 1 week. I interviewed at Pason Systems (Calgary, AB) in Jan 2013
Interview
Friendly. Consists of behavior questions which are pretty standard. That is followed by technical questions related to things you probably would have seen in school. There was a group of 3 people asking questions. After the interview there was a tour of the office and labs which was great.
