They had a workshop the day before a career fair at my school. So I went to both and got offered an interview at the career fair. At the interview I was really well rehearsed on what the company offered because of the workshop. I came off as really outgoing, the don't get very much of that. It took about 2 month to get an offer. Calling them shows your interest so it is not a crime to call them. I called at least once every two weeks, and always remember a thank you letter after your interview.
