I applied through university. Got reply for a phone interview after three months. I have to say it was an unpleasant talk with the HR. I was called the wrong name from the beginning to the end, although I corrected many times (via email and during the talk). The HR seemed inpatient, just read out questions (probably from a paper) and wrote down my answers. The HR also doubted whether I am in Canada (no clue why this is). It was a very short phone call ( less than 5 min) and I was interrupted several times during my answering. I really don't know what was going on from beginning to the end. So my suggestions for other interviewers would be, be prepared to face unpleasant talk. Don't let the cold voice ruins your passion for the position you've applied.
