There are people who do very well on in-person interviews, but do poorly in actual job performance. This article will not likely benefit them. On the other hand, there are people who do very poorly on in-person interviews, but do very well in on the job performance in rare situations that they somehow got hired. Those that don't get hired becomes lost opportunities for both hiring companies and the candidates. The approach is similar to a consulting contract with option to hire. Getting a candidate working for a few weeks or even a few months on an actual work environment as if he was hired should give hiring managers the real deal about a candidate. I don't think the specifics has to be the same, but the general idea or structure is important. This looks like a very promising approach for getting the best possible team. I agree that the article looks like a clickbait and that this will work with smaller subset of candidates. But I think this information is important and it should be out there.
