GSA isn't the most entry level position, that being said it is still a TM position.. Maybe she had a really kick ass interview, and she has a lot of non-work activities to be proud of? Maybe shes the captain of a sports team, and going to college with really good grades, etc.? I wouldn't judge her right away based off her work experience, especially for a TM position... Now if someone got hired as a TL with no work experience that might be a different story...
If shes not doing the greatest job, just remember that almost nobody nails the GSA position from the get go (including myself and my coworker GSA), and it takes some time.
