Northrop Grumman Systems Engineer interview questions

Very fast, professional. First, a 30 min screening, then a Panel interview with 3 people ~ 1 hr. Basically went over my resume, job description, and asked basic questions about skills listed in the job description (Kalman filter for ex). Pretty laid back. Managers seemed nice. Entire process took max 3 weeks. First got an email. Week after screening. week after interview. Got a congratulatory all 2 days later

I went to apply at a career fair at my college, then they contacted me to set up an interview at my college. The interviewer was really nice and was really understanding.
