Received Offer. What Questions do I ask to DD a PE job?

I'm at a megafund and just received a lateral offer for another PE job that specializes in a sector I really like. That said, I'm a little unsure of the opportunity because the people there are a mixed bag than what I'm used to in my current firm (not exactly Wharton -> GS type, but a slight step down).

If you only had a few questions you could ask the juniors on the team to find out whether it's a good opportunity (deal experience / culture wise), what would you ask? Trying not to get catfished.

Thanks.
