Northrop Grumman Software Engineer interview questions

Applied August 16th 2022, and was reached out by HR two days later. My recruiter then set me up with a 1hr (give or take) phone meeting with two engineers. Majority of the questions asked were generic OOP and cpp concepts. Very straight forward and nice interviewers. An offer was sent to about two months later, but by then I'd already taken another position.

Applied online. Got contacted by HR to schedule a virtual interview. As she requested, I provided dates and times that work. In a span of 2 weeks, that same recruiter scheduled 2 interviews I did not confirm, seemingly avoiding the dates/times I had provided earlier! The first time, she called me an hour earlier to "confirm" the interview. I just reminded her that I did not confirm an interview that day, and that I was not available per dates/times shared earlier. The second time, I received a voicemail from a hiring manager; it went: "It's now 6 minutes past, wondering if you still plan to join the call...". What? She did it again? I returned the hiring manager's call, told him I did not have an interview scheduled that day, at least not one I confirmed. Told him this was the second time this recruiter, whose name HE brought up to confirm, scheduled interviews for me without my awareness. Couple days later, my application status changed to, "No longer in consideration". It's mutual!
