I went through triplebyte twice, once in late 2019 and then once again a few months later after the company I landed in shut down because of Covid. I was happy with the process, they promised to take a lot of the headache regarding tech screening and it worked. I think the value proposition is clear - I don't want to do the same tech screens 100 times, and lots of smaller companies may not have the resources or desire to manage high quality tech screens themselves.

To be clear, I'm only addressing the comment about how people thinking highly of them are gullible. I had a great experience, twice, within a few months, and that included going through a time of huge uncertainty.

That being said, I was not happy to see each of the changes they've made over the last year or so, and this does not strike me a good direction for engineers. I suppose I have to agree that they are not doing this from a position of market leadership. Perhaps they were providing asymmetric value to engineers, and at the end of the day the engineers are not the ones paying for the service.
