First official since graduation job interview but I feel like its a scam

Something feels off about the whole thing: 1. The email is vague it says they provide training and no experience is required. 2. The email I got from someone and its not a professional email address.

1. At first, the person said it was a group informational session but its changed to doing it in person. This really puts me off I don't want to walk into something or get embarrassed.

2. The email also says Upon arrival ask for "john" but no last name was given to me.

I know I'm being paranoid but I don't want to drive and fall into a scam.
