During my interview with Sandia this morning, the recruiter asked me about if I dealt with real-time issues when working with cXprop. Unfortunately, I had to explain that I did not worry about those types of constraints when working on my tool. Basically, I worry about code size, data size, and duty cycle. That seems to be it. Occasionally we used to through stack size in there as well, but John does not maintain stacktool anymore, so it does not work for TinyOS 2.
Other than that and a few fumbles here and there, the interview went fairly well. It sounds like they are doing some really neat stuff that I would be happy to work on. I just have to make sure they would be happy to have me work on it for them!
