After applying online, a recruiter for Paychex will contact you. After speaking through the recruiter, who is basically screening you. They next interview will usually be in person with the Hiring Manager (usually the person you'll be working underneath). Mine was a little different as I was in New York and was looking for a job in Minneapolis/Chicago. After the initial "in person"/phone interview, we decided to have another discussion with the possibility of me flying out to Chicago to interview in person, but we were able to do a video call which worked. After that, they made their decision fairly quick and an offer was extended.
