I applied in-person. I interviewed at FIS (Bārdaw) in June 2019
Interview
The interview process was not hard at all.
The resource manager just asked me a few questions to get to know about me and what i wanted to do for my intern.
Then after few follow ups with email i got the intern
After you send your request for an internship, you get an email that you need to do a technical interview in the next couple of days. After you finish your technical interview you get an email if you did or did not get accepted into the next round .
I applied through university. The process took 1 week. I interviewed at FIS (Milwaukee, WI) in Mar 2016
Interview
Very laid back hiring process. It's not your fancy tech company that tries to make sure they only hire the best/brightest. If you know how to code and can fit well into their team, you've got the job. (1) Phone interview with Recruiter who tries to advocate for you. Make a good impression, and don't sound horrible. (2) In person interview with the manager who tries to just gauge your general competence within 30 minutes. No technical questions. They're not huge school or GPA snobs. It's a pretty nice interview process. Just make sure to come up with questions that demonstrate your knowledge of key fields. And as always, "Cracking the Coding Interview" masters won't have issues.
Also, they drug test.
