People notice genuine learners. They'll want to help you. Don't tell them, but they just became your mentors. This is very important: Pick up what they put down. Think of them as offering up quests for you to complete. When they say "Anyone willing to help with __ __?" you're that kid in the first row with your hand already raised. These are senior engineers, some of the most in-demand people in tech. They'll spend time with you, 1 on 1, if you help them out (p.s. and there's always something they want help on). You can't pay for this stuff. They'll teach you for free. Most people don't see what's right in front of them. But not you.
