Apply with c.v. and called in for training a few days later. The training was a few hours and very straightforward. There was no interview process which is great if you suck at interviews.

will ask for self-introduction and invite you to training directly. There is a whole day training afterward. And the training only got paid if you can make successful call within first two working days. If you didn't get any successful call within first two working days, you will be fired soon and got no paid for the training day. But it is not so difficult to get successful call.
