Hi Antonov!
I attended the CTC selections a few months ago. During the interview you'll face two people, one of them will ask you technical or aviation related questions and the other one more "common" ones. Here are a few examples of what I've been asked:
How many hours a day/days a week can an airline pilot expect to fly?
What will you do if you are not successful?
Did you consider the military? if not why not?
If you had to make an unscheduled landing due to a sick passenger, who else would this affect and what would be a result of this?
If your captain was disregarding SOP's, what would you do about it?
What are the differences between an Airbus and a Boeing cockpit?
Have you ever faced a difficult customer during your work experiences?
How would you handle such a customer?
What difficulties do you think you will encounter during training, and after completion?...
As you can see, just like you suspected, there are typical questions.
If you want to know more, don't hesitte to ask me!
Best of luck!
