What is the best advice you could give someone during their first month at Best Buy?

Best advice i can give is you wont know everything right off the bat. It is ok to not know everything and know how to respond to every situation. Don't be afraid to ask questions to your peers or leaders, as they are more than willing to answer and assist. That of course being said, attempt to learn as much as you can, because if you don't there will come a time where you must do your job alone, and if you cannot do it correctly, they will find someone that can.

It may seem rough, some manages love the fact that there in charge so they will let you know, but just keep your head and do your best it will get better
