Firstly, it was a short phone interview with basic questions as well as one behavioral style question. The questions were very easy and the woman was very friendly and helpful.
Second, I was scheduled for a language assessment for the other languages that I speak (this is only a short talk on the phone, only conversational questions asking about your current job, why you want to work at Air Canada, your hobbies, etc. It is about 5 or so minutes in each language).
Thirdly, after I had passed the assessment I was e-mailed an evaluation on the Air Canada website. It consisted of 135 multiple choice questions. You are given an hour to complete the test. The test is skills about Geography, Math, etc.
Once I had completed the test I was later called by the recruiter to mention that I will continue in the process for a 1:1 interview at a location in town. She e-mailed me the details as well as some forms I had to print out and bring to the interview.
Furthermore, the in-person interview was mostly more behavioral style questions. The questions were not difficult and was only about twenty (20) minutes in length. I was given a role play scenario as well. I was told to wait one to two weeks to hear back.
