Lockheed Martin interview questions

The hiring manager was really friendly. Asked the typical behavioral and cs fundamental questions. At the end, there was a coding problem but he said he didn't want the code but just wanted to see my thinking process.

Tough interview. Kept an eye on glassdoor and was expecting a easy interview. NOT. Constant questions, behavioral questions mostly with technical aspects embedded in. Be prepared. Basic requirements will be asked extensively. Exp helps, certs.
