Singlewire Software Software Engineer interview questions

The interview was not terribly long - an hour or so with a small team, and then a half hour product demo with one other person. The conversation was good with all the groups. Everyone was friendly and interesting. There were a few cons to the whole process: after my interview, I got virtually no follow up for almost three weeks. Then when I contacted the person in HR to try and get an update I got a bland form letter as a response within a matter of hours. I don't mind not being chosen - I'm sure they have a zillion well-qualified applicants, but three weeks to send me a form letter seems a little long.
