What are the return rates for EBs?

Choosing between BB vs EB internships and was wondering what’s the return offer rate for EBs like PWP, Evercore etc.? I assume COVID affected things last summer but for anyone who just did the internship this summer, do you know what’s the percentage? I hear a lot of varying information even for the same company so would appreciate some insight.

This year they were mostly pretty high (think 90% or higher). There are people saying PWP was around 75% this summer but I think that’s an anomaly
