Advantage Route Systems Programmer interview questions

Interview was pretty easy and simple. They were quick to respond to my application and setup an interview within a few days (seeing as I had applied on a Friday and was in their office Monday to interview). They offered me the job the very next day, met with them in person to have a verbal agreement and go over my path from tech support, to become familiar with their products, to developer. The next day HR sent me an email outlining my benefits and whatnot, all I had to do was reply to accept. I decided to negotiate for a higher salary and the owner extended a new offer. Some context behind that deal: he emailed me the counter after work hours around 7pm. I thought ok great I'll accept the next day. Well, before I could he emails me again pulling the deal right from under me, "regretfully the position is no longer available to you". I thought that was extremely unprofessional, and they showed their true colors; guess I dodged a bullet. He probably wouldn't have given me the raise we discussed since they don't "write things down" if he was going to be shady like that. Oh well, onto bigger and better things
