Here in Seattle, if you can't quickly solve Fizz buzz and Hacker Rank questions in an interview, most companies interview processes will reject you in short order. It doesn't seem to matter if your getting quality PRs approved into popular FOSS software, nor do most interview processes actually vet for technical capability or quality. My friends who work in tech right now (whether at Amazon, Microsoft, Google, Mercedes, etc) essentially set aside 6 to 18 months prior to job hunting to screw around practicing these questions.
