The process took 4 weeks. I interviewed at Lockheed Martin in Nov 2010
Interview
There was a technical interview and a behavioral interview. Both interviews were with a panel of employees. The behavioral interview consisted of the standard questions while the technical interview was to determine your past experiences, mental capacity, and ability to convey your knowledge to others.
I applied in-person. The process took 1+ week. I interviewed at Lockheed Martin (Washington, DC) in Jul 2009
Interview
I was fortunate enough to have an inside contact in the company. My friend passed along my resume to one of the directors in the company. From there, he sent out my resume to a number of managers. My interview was very smooth. I talked to three managers all which had the same basic questions regarding my prior skills and how they could relate to the future job. I found everything very professional.
