If I were sitting at my desk and a new person walked in (Me) I would probably hire myself for three reasons. First, would be that I'm trustworthy. Lots of people tell me that one of my great qualities is that I'm trustworthy which can help. Second, is that I'm loyal. Being loyal will really help to maybe have a better relationship with the other employees or my boss.
Third, Would be that i'm reliable. Being reliable is alot of help because usually boss's like reliable people better.
