BD Program Manager interview questions

contacted by a third party recruiter, Adam who is looking for program manager on behalf of BD, extremely nasty recruiter, kept picking on my words (English is my 2nd language). and hung up on me because I often used words 'maybe', 'I think'. and he felt that I was honesty with him. I appreciate your suggestion but you don't have to insult me on the first phone call. I am not sure why BD would choose such an irritable person to work for them, especially as a recruiter.
