They will apply stress interview technique, which mean they will continuously throwing question at you to test your ability to handle stress. Mainly because the job required facing huge group of people during providing training, yes you will be providing training to your colleague. Then there will be question bout how you handle the struggle, challenges and so on.

There are three session, technical, behavioral and stress interview. I basically panic at stress interview. The interviewer is nice but due to job requirements they have to conduct stress interview to identify the true candidate, which I am not one.
