QualityAI Front End Developer interview questions

The technical interview went ok, shortly after the company came with an offer that I accepted. I asked to sign the contract before announcing my resignation from my current job and in about a month I was going to start my new job as a developer at Qualitest, which should have started with a 6-week training program together with other new colleagues . A few days before starting work, I was called to be told that the program was canceled and the company could no longer honor the offer and the contract. And that was all I was told, I didn't receive any other details, not even an apology and this is how I found myself jobless, with a mortgage and a family to take care of. Thanks Qualitest for leaving people jobless, announcing them in the last day possible so they can't take their resignation back.
