I did triplebyte most recently in mid 2019 and that was my experience as well. I used triplebyte as well as job searching on my own and I got a few offers from triplebyte, some of which seemed like interesting projects but couldn't offer a level of compensation that would make the risk worth it. I got two high-quality job offers from my own search, both of which were more compelling than any of the triplebyte offers and I am still with the company whose offer I accepted.
The "super week" of onsite interviews was interesting, probably increased my overall interviewing skill, but was probably one of the more stressful individual weeks in my life.
