CPR+more interview questions

I just emailed the company and one of the employees told me to contact another individual, I suspect, either, the individual in charge of hiring people or the owner. We talked over the phone and he asked me a series of tech questions. I was able to anser most of them, solidifying the fact that I knew something. He then invited me to come in for a 1 to 1 interview. Aside from examining what I did know and didn't know, the friendliness of the company really stood out. Of course, a part of that probably came from the fact that they were a nerd based group. So, it was easy for me to hit it off with them. But, in general, they were easy to get a long with.
