Northrop Grumman interview questions

One of the worst experiences I have had in my life. I interviewed for the Linthicum, MD, position. The interview was easy and great, and two days after the interview, I was selected. The recruiter called me and said they would give me a certain amount of money, and I said that was the amount she had mentioned earlier, and I was okay with their offer. Then she said she would be in touch, but she never got back to me. I never declined the offer or negotiated the salary but was still rejected by the hiring manager. They never tried to make me an offer; they never tried to reach me. This is not how you should treat people. Don't make them an offer if you are going to do this. I hope karma gets to the recruiter and the hiring manager for how much anxiety and depression they have caused the other party.
