Just wondering what questions they ask in Phone Interview and Face Interview? Thanks

Both are behavioral type questions. 'Tell me about a time when you had to cope with a coworker who was difficult' for example. If you google behavioral interview questions, make a list of 20-30 and come up with answers to all of them. This will get you thinking about those types of situations. Then you will be ready for your interview.

Also, make sure you have a very solid answer for when they ask what you know about Nav Canada. go in to detail.
