Sounds like a different offer. interviewing.io prepares you for interviews, while the triplebyte reboot is a way for companies to outsource their interview process. I think it makes a lot of sense. Interviewing, or, more generally, filtering the 1% of good candidates, is a difficult task and could be indeed a job in itself. The company has a strong incentive to take this job seriously since they will acquire a reputation after some time and will lose clients if it turns out they are being too lenient.
