I don't mean completely in person, but I do expect a lot of companies will want to meet the person in real life at least once. Which adds huge logistics problems.
Btw I'm not saying 'cheating', that's one thing. I am meaning industrial scale fraud with remote candidates. Eg having one person interview then another (much worse) person gets the job. There are gangs that are going to almost unbelievable lengths to do this.
It's wilder still that the handful of times I've dealt with this have all been before RTO!
