I applied through college or university. The process took 1 week. I interviewed at CME Group (Chicago, IL) in Jan 2018
Interview
The first round was a technical interview. The guy was nice, however I was stuck on many syntax errors and he didn't notify me that I was able to use google until I had 5 minutes left. So I just relayed my idea over to him. Never heard back.
