I applied through university. The process took 1 day. I interviewed at HSP (Melville, NY) in Mar 2015
Interview
Interviewers are very friendly. Interview was not technical and was meant to see if you care for the business and if you'd be a good addition to the team. It was more of a "get to know you" sort of interview involving questions about why you're interested in developing, what's your thought process like when starting a project, talking about your previous projects, etc.
There was a short test on basic C# after interviewing with two interviewers.
