Northrop Grumman Sr. principal software engineer interview questions

One phone call talking to multiple managers. they asked questions and just need to answer. no coding questions. Just about what I do based on resume. a couple tech questions

Basically three people on a video call. I think it lasted about an hour. They were very interested in my knowledge of software testing. I haven't done a lot of testing so that was difficult. The other questions were fairly easy. I seem to recall a mix of personality questions and tech stuff related to C++.
