Northrop Grumman Avionics Engineer interview questions

The recruiter reached out a week after applying, set up a phone interview, and the hiring manager never came to the interview. I honestly felt stood up and had to reach out with HR to find out what happened. Turns out the hiring manager was too busy in a meeting and didn't care to send an email to let me know he couldn't make it. I would not suggest applying to the Chandler, AZ, office since obviously the applicants are not their priority. Very disappointed.
