Northrop Grumman interview questions

Applied online, and had a HR representative call me the next day to schedule a phone interview. The call with HR was very abrupt and she hung up before I could ask relevant questions about the role. HR informed me I would be having an interview with the hiring manager. When I call in, turns out it’s a panel interview with 4 engineers instead who all asked very technical questions, which took me by surprise. The position was falsely advertised as a telecommuting position, but required full time in the office with lots of travel. After the interview I got a call from the recruiter to discuss my salary expectations and received an offer a few days later. I declined since the position was not what I thought it would be and the team wasn’t a good fit.
