Since it was an interview. I had it over the phone. Then they asked for my resume and pretty much sent it to a project lead who needed an intern and then they would decide from there.
The interview process was nothing too difficult. They asked many of the questions you might expect such as why do you want to work at our company and questions along those lines.
I filled out the online. It was quick and easy, they called to schedule an interview. The person who was interviewing me was nice and very detailed. Overall, they were very inquisitive and welcoming.
