Paychex interview questions

It took 3 rounds of interview including HR, Overall experience was good and The Manager was so friendly. In the second round there were 2 US Paychex employees and I have answered almost every questions they asked . Overall it was a great experience.

Very odd interview process, I have a bachelor’s degree and they only wanted to pay $13 so that was a no from me but the funniest part is they rejected me and I could not even understand why. Now I work for their competitor and I get complaints about Paychex and how terrible it is all the time so it just seems like a very shady company.
