Is this real or fake?

I recently got call on Tuesday for job interview from small firm.It was basic introduction call.They asked every details about my previous experience everything.And just scheduled interview.Weird thing was lady didn't told anything about her firm she is Co-founder there.Also it consist of less than 10 people I guess.I searched on LinkedIn barely 40 followers.What do you guys think about this?I mean I do have gap from August 2023 but I don't just want to join anywhere just for sake of having job because satisfaction in job is more that matters to me.
