Meta Data Science Onsite Interview

Hey everyone, I am studying for the 2nd round interview for the product DS intern position at Meta. Could anyone give me a general expectation for this round? I heard there are no more SQL, but there will be another product case plus some stats questions.

Could you also suggest some resources to study for these stats questions? What type of stats questions will be asked? I'm so in on this, so I'd appreciate any help! Thank you y'all and good luck to all of you!
