People skills do not have to mean being a good socializer and spending a lot of time chatting.

To me People Skills are being able to work effectively with people to get the desired results. This includes different cultures.

Some people I work with like to spend 5 minutes at the beginning of the meeting asking how I am, etc. Some like to just get down to business.

Being able to work effectively with all different people types and not be thought of as rude or arrogant is having People Skills.
