Heck, even had one code challenge pre-interview a few years back at x2-x3 the salary I was aiming for at the time, for a C++ role, even though my total experience of C++ is half of one job that I only stayed in for about 15 months. Obviously I didn't get that interview let alone the job, but that's why they don't just rely on the contents of self-promotion documents we write and which they barely read.
