80% is about what I remember. Haven't given that test since 2015 when I left that job. But yes, your solution would have been acceptable: it didn't even need to compile, or be bug free, just show a clear logical path to the solution. The point is that the vast majority of candidates, including some with Master's degrees in CS, could not write even a pseudocode solution to this problem. It got so bad that I started doing a verbal fizzbuzz test during the phone screen so we didn't waste so much time.
