I'm surprised that I'm mostly 3s and 2s after 4 years of experience at Intel and 1.5 years experience doing side work at college jobs. Working on many projects has allowed me to focus strongly in a few areas. I'm still a "1" in TDD because I only write unit scripts after the code is written and focus more on getting stuff accomplished.
