did you get the same DistinctPIIValuesCounter starter code or was it a different variant? trying to figure out how consistent this one is across candidates

same starter code as far as I could tell, the DistinctPIIValuesCounter class name was identical to what I've seen mentioned elsewhere

affirm gave me a really similar problem a few months back, the propagation part is what got me too honestly

yeah feels like there's only a handful of problems in rotation for this phone screen, seen this one come up a lot

60 minutes for one problem is rough with that much starter code to read through, good writeup though
