<human>: I'm only 22 y/o so please forgive me if this is something standard but I have never before been to a "meet and greet" interview.

I was called yesterday by an HR Representative of a company that had posted a job online with little to no details for a Customer Service Rep/Sales Rep. She told me she could pencil me in for an interview the next day so of course I accepted.

I got to the interview today where there were around 5 more applicants just in the waiting room for my same time which confused me a bit. I got called back to the interview room where they basically pitched me some thing about how they sell thing from kiosks for about 2 minutes, asked me if I understood, and then showed me my way out saying I'd get a call back next week for round 2?

Wtf just happened? I feel like I got tricked into showing up for a sales pitch? What do they have to gain by doing this besides being able to discriminate based on your age, gender, nationality, etc by having you show up in person before they interview you?

Can you condense the text into three sentences or less?
<bot>: wtf is a meet and greet interview? I've read online it's where they see how you assimilate with your co-workers but at this meet and greet I did none of that so what's the point?
