Irina: Previously we provided audition once a year, but the load was growing, and we simply did not have time to train our new guys. Therefore, now we recruit every two years. The next set, by the way, will be just this year, in September. Sometimes the guys leave us because they can't cope with the workload of their studies. As a rule, this is the 1st or 4th course. Then we call those who did not pass the second round of audition to their places. Sometimes we take more people than we planned, with the expectation that some of them will leave in six months. But they still don't leave at all! Then we don't recruit new ones.
