TransPerfect Customer Service Representative (CSR) interview questions

I had 3 interview rounds. I interviewed with the VP of Sales first. Second, I spoke with the Program Manager who would be my manager. Third, I spoke to another salesperson who has worked at the company for a few years. I had a negative experience because I had to follow-up with the recruiter to get next steps. They told me I had the job, but it took them a month to send me the offer letter.
