He got 14 interviews from 54 companies. As a candidate, that's better than what you can expect from Triplebyte, which apparently only interviews 1/6th of applicants (2000 interviewed out of the 12000 who have applied).

If you don't make it to the interview phase with Triplebyte, then the process might as well be as opaque to you as any company. You aren't given much information about how well you tested and the reason you weren't selected to interview.

It would be great if there were a Triplebyte-like service for those of us in the lower 10,000, but until then it's back to applying to dozens of companies.
