Can someone explain why auditing companies send auditors and then they leave and then send different ones back

Question

Our company hired some auditors to come audit the company, obviously. In May, there were about 3 girls (who i am pretty sure were the first auditors..) Then, the 2nd week of June, 3 guys came. Today, 1 of the guys is still here, and the other 2 are gone, replaced by 2 VERY obnoxious girls. Why did the place they work for replace the other 2 guys with these new girls? They are very annoying and I was interested in one of the other guys....will they be back? How does this work???

Answer 1

I assume this is a Big 4-audit firm (because it's typical for them). They send their juniors to their clients so the juniors can learn.

They have a big name so they can get away with it but it does sucks for their clients.
