Got an interview with a marketing company but things seem a little off

Lately I’ve been applying to a lot of jobs and came across an easy apply on LinkedIn for a position with a marketing company. Less than 24 hours later I got a response for an interview and they seem to be trying to hire on a lot of people due to quick filling interview slots. I tried to do more research about them online and can only find their website and LinkedIn. They also claim on their website to have multiple branches but I can only find the one at the location I applied to.

This seems off given that other companies have taken way longer to get back to me (if at all) and have at least a Glassdoor if they’re established. Wondering other people’s thoughts and advice going forward.
