my advice: treat debugging as your core competency. When you get stuck, avoid asking for help until you've tried pretty hard to solve it yourself. If your any of your peers gets stuck with an interesting problem, go help if you have spare time
Yep, it would be annoying if every junior/intern I was mentoring asked for help without attempting to at least Google it first.
Although, on the other end is people that spend way too much time attacking the problem with limited context, and then asking for help after the day is almost done.
