Do what's asked of you. Do a bit more if you can. Help others. Ask questions if you're stuck, but only if you can't find the answer using Google. Join in when people are talking things through. Speak out when you think something is wrong (or right). Question assumptions. Respect the opinions of the rest of the team. Show gratitude when someone helps you. Be honest. Accept some of the shit jobs - everyone does them. Don't let people treat you like crap - you're there to learn stuff. Try not to take sides. Join in the non-work things. Have fun.

All this boils down to a single very important rule: Don't be a dick.

Very good advice. Be a good guy / good employee, not just a strong technical contributor.

Couple of qualifiers to: "Do a bit more if you can"

- don't over-reach, doing stuff no-one's asked for could be a negative, and

- don't be too pushy about "new ideas"; you might be right but as a new start you do not want to rub your colleagues up the wrong way until you've built a good track record and some respect within the org

Edit - plus buy the team cakes and chocolate sometimes :-)

Taking ownership of a problem they caused. Giving more credit away than they take.

Put your hand up - always be the first to volunteer for a project or help out

You can't go wrong with bringing fika.

Be nice, polite, keen and humble.
