Is the speed of this job offer sketchy?

I applied to a bunch of online postings and was offered an in-person job interview. They asked me to come in the next day (today) where I was told they were impressed and told to come back tomorrow for training.

The firm is a consulting firm but basically no information exists online so I assumed it’s new. I’m also a recent graduate with basically zero relevant experience.

However, I received an email confirming that I was to come in tomorrow for training however the email was sent and delivered to my email while I was still being interviewed? The time of the interview was 1:30pm and the email was delivered 1:35pm. I hadn’t even left the room yet.

I will go tomorrow. But does this raise any red flags to more experienced job seekers?
