Northrop Grumman Software Engineer interview questions

Basic STAR questions were asked, with a good amount of small talk in between. No technical questions, all questions were behavior or pertaining to my resume. Built up acquaintances with recruiters that helped secure the interview.

Went through the resume and had a conversation about past projects. Nothing specific. Almost no technical questions except do you know this tool, have you used this technology etc. Declined at the end because they offered a massively low salary for a senior position (almost 35% below market value). Felt like they were just trying to get recent graduates but somehow accidentally called me in for an interview.
