If you're working at a software shop that doesn't even use source control I suggest you get out of there ASAP. It's one thing to be missing core tools and methodologies when you're applying for your second job 1-2 years in, but if you hit the 5 year mark and have zero familiarity with source control or web services (for industries where this is valuable), etc. you're going to get passed over for interviews. Staying there may be causing irreparable damage to your career.
