I'm considering something similar. I code for fun regularly but I worry if I'll cut it as a modern coder. Check in code to prod on day 1 seems to be a considered a badge of honor these days. I worry that I'll bring down the site :-p Also, 7 years ago, methodologies such as SCRUM and TDD weren't pervasive. How are you adjusting? Also, how did you prep for the technical interview?
