> At how many lines of code can I call myself proficient in a language? I would say don't use adjectives to describe skill level. I put most languages I have experience with on my resume, and order them descending by how well I know them. I know the stuff at the top pretty well, and it's downhill from there. In interviews I'm very upfront that I'm incredibly rusty with the stuff on the bottom of the list, and interviewers understand and accept that. The exception is if you feel comfortable putting "advanced" or "expert" on one of those, but then you had better be able to back it up. LOC is a bad measure of proficient. I would say you're proficient if you can write a simple program without looking up syntax and relying only on autocomplete for library references.
