So we added an option to interview by way of a paid trial period (work part-time nights/weekends for a few weeks with the hiring team). Figured maybe some people might prefer that, but probably wouldn't be feasible for most.
Every candidate since has chosen that route, with very good outcomes - so far, everyone who did well in the trial period has been a good hire. Some of our best hires did not interview well (and would not have been hired under our old process), but were outstanding in the trial period. And, a couple candidates interviewed so well we almost skipped the trial period, but they struggled to complete even simple tasks during the trial.
We've now optimized interviews for that process, where the decision is primarily about whether it's worth moving to a trial period. That usually only takes a short screening call and a 1-hour call with the team (we're a remote team, even before quarantines).
BTW, if you'd like to experience this first-hand, we're hiring - https://news.ycombinator.com/item?id=22753515
