tl;dr - I tried Hired. I highly discourage anyone considering signing up from doing so.
Hired plays the game well at the recruitment stage (as evidenced by this ad) but the actual experience is nothing special at best, and mind-numbingly annoying at worst.
At best, the "talent advocates" are useless pests.
After filling out all my personal info, completing my profile, and passing the entrance exam, my "talent advocate," supposedly my personal point of contact at Hired, insisted on a phone call "to introduce me to the nuances of the platform" (i.e. a poorly disguised screening call - honesty would be appreciated, Hired). Long story short, that call never happened because the advocate repeatedly called far outside of the day/time ranges I provided (8:30pm is not an acceptable substitute for 1-5pm).
Later, I requested to opt out of the weekly auction I was placed in because it happened to fall on a very bad week for me. Note that a previous email from Hired specifically said that was an action I could take, yet my request to opt out was completely ignored. Upon returning, I was frustrated to discover that my account showed multiple warnings about not having responded in a timely manner to offers. I declined the offers (see the next section) and gave up on Hired for a few months.
When I decided to give Hired another try by requesting to be placed in another auction, I eventually received a terse email from my "advocate" informing me that I would not be allowed to participate because I had not responded to his request for a brief chat.
The kicker to this whole point is the entire Hired process could easily happen without talent advocates - I never spoke to mine yet I went through their entire process (sans accepting an offer). They are pointless, yet a client may be punished for never speaking to one.
The positions for which I received offers were no different than those from average recruiters.
The vast majority of jobs that recruiters contact me about have nothing to do with my experience or skillset. The offers that came through Hired were exactly the same. Not only were the offers for jobs I wasn't qualified for, there were mentions of "meeting for coffee in the next few days" when the headline of my profile made it clear that I currently lived in the midwest but was relocating to the bay area in six months. Any reasonable, actual offer would start with a phone or Skype conversation before forcing me to fly out. It was very clear that the companies were not giving my profile or CV even cursory glances (much like typical recruiters). Beyond that, two of the positions for which I received offers I was already aware of via recruiter calls. The offers I received via Hired essentially equated to spam.
Attempts to contact Hired to discuss these problems were completely ignored.
As one might expect, further requests to my "advocate" were never responded to. I wrote a message to the support team explaining my difficulties and again asking to at least be placed in a forthcoming auction, and hopefully be given a new talent advocate. My message (several months old at this point) never received a response.
