Lockheed Martin interview questions

I interviewed at Lockheed Martin in the summer of 2009. I applied through their website and was called for a brief phone interview with a person from the Human Resource department. At the end of the interview I was given a time and date to meet with the person who would be my supervisor. I was told that the interview would last for no longer than an hour. When I got to the Lockheed Martin, I found out that I had been given the wrong building number and had to go to a different building. Fortunately, I had arrived early. When I got there, I was interviewed by two people who were very nice and spoke highly of the project that I would be working on. After this interview I was given an assignment to work on that took about two hours to complete. The assignment was to research and write about a rare genetic disease that they had chosen and then to translate the information into Spanish. The total amount of time that I spent at the interview was three hours. This was upsetting because the time slot that they gave me for the interview was at noon which meant that I missed a late lunch appointment that I had with a colleague who worked in the area. Three weeks later I had not heard back from Lockheed Martin. I called the Human Resource person who I had originally spoken with, and she told me that Lockheed had lost the contract and that they no longer had a position available. I was upset and disappointed to hear this because I had specifically asked during my interview about the status of the contract, and they had told me that Lockheed would have the contract for another three years. Overall this was a very bad experience and I would think twice about applying to another position at Lockheed Martin.
