I applied through college or university. The process took 2 months. I interviewed at Paycom (Oklahoma City, OK) in Oct 2017
Interview
The interview process was amazing. I applied through my college job portal and got a call to complete an online assessment. The questions were easy and covered basic knowledge of php, sql and oops concept. Next round was hosted by the university which was a mix of fairly easy technical and behavioral questions. After two days I got a call from the recruiter who informed me that I was selected for the next round. I flew to OK for my final round with a senior manager. The interview was for half an hour and had similar technical and behavioral question set.
I got a verbal offer in 3-4 days. Overall a great interview experience.
