I applied online. The process took 2 weeks. I interviewed at The Pinnacle Corporation (Arlington, TX) in Aug 2013
Interview
It was a one on one interview after our initial phone call. On site, I filled out an application. The interview went great and we probably got into a deeper discussion than usual because it was a lot like a previous job I had, but a different industry. After the interview I was given a tour of the building and it was pretty cool. I got to see the QA Lab and the vault (it's in an old bank building). I had a great offer, but I declined only because it was on the other side of town for me, and I wasn't ready to make the daily commute. If you're in the area, though, I would recommend checking them out if/when they have openings.
Interview questions [1]
Question 1
Basically just asked about my experience as a SQL Developer. It was more discussion based, rather than "Do you know x y z and can you repeat the datatypes of SQL Server". Those interviews suck, but if you like them then feel free to apply at Six Flags.
