Master's GPA for MBB?

Is there a cutoff for Master's GPA similar to that for undergrad?

I am at a top ranked Swiss university studying Statistics/Data Science, and the grading system here is pretty brutal and very different from what's in the U.S.

Grades are given on a best out of six scale, and it's extremely difficult to get a six here, at least compared to what I've seen as an undergrad at a target school in the U.S (I have 3.9 undergrad). I am hoping to manage 5.3-5.4, but even that's not easy at all...

Do U.S. offices just linearly interpolate numbers? Or do they adjust for grade deflation for European schools?

Or are European schools just so under the radar that they'd just get brushed off?

Any input would be appreciated. Thanks.
