During the interview, they mentioned that your performance needs to generate several times your salary, that you will be subject to review, and that if your performance is poor, you should quit. They said there are many interns because they had interviewed many people but felt none were suitable, so they decided to train people themselves. Nothing else was mentioned during the interview.
The interview was supposed to be an opportunity for both parties, who did not know each other, to get acquainted, but they talked only about themselves from beginning to end. It seemed there was no need to schedule an interview at all.
