It was the single worst experience of my life interviewing with them. I started the application back in November, don't hear back but attend a live in person conference in February. There I was granted an in person interview where I impressed the manager there and he recommended me to the mission sector team. I don't hear back for another six weeks in march. Where they had me attend their virtual career fair where I had to wait in queue for one hour each to talk to two recruiters and HR. We were only granted 10 minutes each but I made the best of my situation and impressed the two there as well. They tend have me attend another interview event in Baltimore relating to a group interview panel. The entire interview took 6.5 hours and the recruiters there invited me to a software engineer interview, a position I was never qualified for or had any chance of succeeding. The worst part is they call out everyone at the event they wanted to hire one by one and tell them they are writing the offer letter as they speak and left the rejects in an isolated room. The recruiters there lied to my face, knew I didn't get the offer, and isolated me from the rest of my group in a dark corner because the hiring managers decided I wasn't qualified for a position I never applied for. They then wasted even more of my time by forcing me to wait for everyone else who got their offers to leave before I was let out of my corner to finally go home as if it wasn't bad enough I didn't get the offer but they had to waste even more of my time by making me the literal last person to leave the hotel. And to make matters more convoluted, they post three new model based/architecture systems engineer positions that I was qualified for the night before the interview but never granted me a chance to interview for that area of specialty. Before this interview process I looked up and idolized Northrop Grumman as one of my goal and dream jobs and they repaid me by stringing me along, giving me false hope, lying to me, isolating me, and effectively screwing me out of a job I was qualified for by posting the jobs right before my interview. This entire process took 6 months and I came out of it looking like a chump and absolutely worthless. If they want you for the job, they will bend over backwards to get you an interview but if they don't want you they will essentially treat you like trash. I have never lost so much respect for a company I used to admire and look up to as much as Northrop Grumman and never been treated so poorly during an interview I almost wanted to cry.

Thorough and standard interview to assess your level. Mainly asked me to introduce myself and what kind of experience I have. After the interview, I was given an offer in a week.
