is it just me or is there never any availabilites on interviewing.io for mock interviews?
Not a scam. I used it 2 years ago and it has helped me. Got me an interview at SpaceX, Cruise and a few startups. I was interviewed by an ex-Amazonian on that site and ended up accepting an offer from Amazon.
I think it's a scam to grab your email
Never heard of anyone actually getting an interview
