Northrop Grumman interview questions

First stage interview was to assess suitability for second stage interview, it lasted about 45 minutes and just asked about previous work experience. The second stage interview was about 2 hours long and was based on competency-based questions, based on the NG values e.g. we believe in innovation, give us an example of a time you came up with a new solution. The interviews went well, but they strung me along for months before withdrawing the offer. Every few weeks they would negotiate me down on salary, in the end it was nearly £10k lower than the advertised role. It's really upsetting that they operate like this, I have read it was a slow process, but this really took a lot of time and effort, I'm devastated that they treated me like this, over such a long period (4 months). I hope they don't treat everyone like this.

Hiring managers mostly just asked about my experience, how I approach certain problems, and how I would react to situations that they outlined. Two interviews conducted over a phone call and took about an hour each.
