Plaid final round confusion

I’m interviewing with Plaid right now and I’m really confused about their interview process. I just had what they said was the “final round” but the recruiter just asked to schedule another “final round/technical deep dive”. Is anyone also interviewing with them? I really don’t want to prepare for another final round…

that’s really weird, I didn’t have this extra “final round” before the actual final onsite. Also I don’t know anyone that got an offer there so who knows what they’re doing
