I think a lot of engineers get to this point through different methods.
For me when I was new engineer (no CS background) I'd never spend too much time on a bug before I got frustrated and would head over to a more senior engineer's cube for advice. Usually during the walk over while I tried to properly form the exact question to ask I'd figure out the answer. Dan (my go to guy for this) got used to seeing me head his way then just say hi, he'd ask "Figured it out?" and I'd say "Yep" and head back to my desk.
