Not helped by the fact a lot of interview processes - unless you can rely on word-of-mouth and the corporate structure allows for shortcuts - are byzantine, maddening and/or don't have much relations to the work one will be doing afterwards. No fuck you I'm in for a sysop/cloud position, I won't waste my time doing Fizzbuzz. Give me a laptop with internet and an actual work task if you want to judge my competence.
