Epic Games Engine QA interview questions

Was in an interview process for about 4 weeks. The interviews went very well and seemed to mutally exciting. They seemed really excited about bringing me on. Eventually they told me i had the job and they asked when i could start. I told I had to put a 2 week notice in for my current job and they so the start date. They brought me in to do paper work to finalize the deal which i did and everything again was fantastic. On the last day of my 2 week notice they withdrew the offer. Which left me unemployed with 2 kids to raise.
