Are these financial jobs BS?

[sushijerk]

Situation: I'm a biomedical engineering major about to graduate. Most BME jobs require a graduate degree so I'm having trouble finding jobs in my field, even though I have decent experience/internship.

A lot of places like Prudential(is this insurance?) /Citigroup/Edward Jones have seem my resume through the school network/Monster and are calling me and asking me to callback/interview. I'm naturally suspicious of jobs that seem to knock on your door, so should I even bother responding to these places? Is this a legit job or do they just spam every resume to get try and get salesmen?
