Lockheed Martin Software Engineer interview questions

Had an in person interview in a big room with a long table with 9 people asking me questions about my resume and behavioral questions. At the end they gave me an easy coding question. After that they gave me a tour

Presented as a Skype Video Conference. It was actually Skype for Business(Microsoft Lync). No one there seemed to know how video conferencing worked. The day before the interview the HR person asked me to help her get her laptop to work from home. She was not successful. The day of the interview there were four people in a room who positioned themselves so only two of them could be seen at any one time. I ended up talking to people who I could not see. Why were we video conferencing? The interviewers were unprepared and bored. One HR person I worked with left the company soon after the interview. The other HR person declined to answer my emails afterwards. So much for Lockheed's promise of interview feedback.
