How does this work if candidate has experience in, say, backend, but haven't worked much on frontends or mobile apps etc? A specific "take home" task puts those candidates at advantage who have already worked in related area, have written code that they can immediately reuse or are experienced in frameworks that allows them to fast trek. This would be great if the job also required exact same capabilities for the foreseeable future from the candidate. However it would overrate or underrate the candidate if the job requires candidates to work on diverse set of problems in long run (for example, switching from MySQL to graph problems). It would be interesting if article also gave few examples of such "take home" tests.
