First mention I see of hired. Used it while I was looking for jobs in London - definitely something I can recommend to get your foot in the door, especially for people who need visa sponsorship (at least that was my scenario)
I would say that I completely underestimated the amount of time required for it. It skews more towards startups, and it seems like take-home problems have become the norm in their application processes now. If you're going to take this route, I would recommend taking 2 weeks PTO from your day job to dedicate to this.
For my last job change, I took a much more passive approach. Over a period of a couple of months, I engaged with a couple of recruiters who reached out to me, only interviewing at 2 companies, and then took this job. Far more relaxing and less pressure. The only downside is that I felt like I had less negotiating power at the end.
