First step is a call with a technical recruiter. They will basically try to convince you why Paycom is a good place to work. You should expect the "Why you want to work at X place" question. First interview is a technical interview in the language of your choice. I was expecting it to take 45-60 minutes, but it barely took over 30 minutes. The question was probably an easy LC. I heard that the last round was an HR interview. I did not follow through the whole process, so I wouldn't know what kind of questions they ask at that point.
