SAIC Engineer interview questions

Straight forward and easy. A panel of technical folks participated in the interview. Nothing challenging. Each panel members asked 2 questions and they were broad questions. Straight forward and easy. Straight forward and easy.

The interview went well except for one lady looking to find faults. After the interview, I was offered the position. I sent a thank you note the next day and was sent a system generated rejection letter two days later. I emailed and called the Recuriter to find out why my verbal offer was rescinded and ingnored. I had several employee referrals and other managers were going to interview me there as well. It is my understanding that I’m now blacklisted from this company for reasons not known to me or the employees who referred me.
