I feel the exact same way. I went through the interview process with a handful of good startups through Triplebyte (and got offers from almost all of them) and even though I ended up taking a job with a company outside of TB, I still walked away extremely impressed and confident that I'd use the platform again in my next search. I loved that I was pre-qualified and didn't have to intensely prove my technical chops at every on site. With this change, I don't see the benefits for me to use TB over a competing job board or just applying to companies directly. With these changes, I don't plan on using TB for my next job search.

Edit: just saw the comment that TB is keeping the quiz. Would consider using the platform in the future as long as that pre-qualification track is available and that this new direction is just a superset on the existing TB features.
