I just talked to a secret source who interviewed to be a Pad Squad last year. She couldn't do it because her schedule was so tight the first part of the year. She said there is a three person panel headed by someone named "George". Almost all of the questions are about how you would react to drunk guys hitting on you and drunk guys yelling at you. I heard rumors that this coming year that they are adding questions about how you would react to internet nerds talking to you.
After that it's questions about your favorite Padres memory and about the first time you went to a game. Stuff like that.
Remember Pad Squad applications need to be in by January.
