Ask questions, no matter how stupid they may be. REALLY. Ask any doubts and questions you may have regarding coding practices, implementation details, technical workarounds, etc...

Even if the questions sound silly, which is what terrifies the most, just ask. At my first job, I was too afraid of asking my teammates unless I came up with some smart-sounding question.

Fast-forward a couple of years until now: I have a teammate who is quite less experienced, and revealed me he does not want to ask questions because he thinks it's a waste of time for the other person and/or he feels silly to the whole team.

I attempt to mentor him and teach him to ask questions, no matter how dumb may be. We've always been there.

This leads me to another aspect: have empathy towards your colleagues.
