It was the worst experience ever. I interviewed with 4 different people, but one of the senior toxicologists was very mean and asked me every single detail from my resume. He was very rude, and his questions were not totally about the position. He just tried to find a question that I could not answer. The other 3 people were nice. But after the interview, I sent an email to the director about that senior toxicologist's attitude. I felt terrible for a long time.
