At least to me, team player means someone who is able to get along well with their team mates in a professional setting. On a personal setting, I don’t care if they are friends or not, but it does help. Someone who is willing to help and contribute to the greater team objective. Doesn’t think or work in a silo mindset or be super calculative on ‘I did this and you did that’.

This does not mean I expect the person to just take on whatever extra work his teammates can not.

Honestly it just really depends on your boss and what kind of environment they were brought up in.

TTDI Shell station. Also I think the Petronas at Penchala Link
