Desventajas
Low salary: I started the process of exploring employment with Lockheed Martin, by speaking with a recruiter. Among other things, I discussed the salary I was looking for. The recruiter said the salary was within range, and set me up for multiple interviews. I spent several hours on the interviews over the course of several weeks. After multiple interviews, they made me an offer that was $50,000 less than what the initial recruiter told me. The salary offered was way below market for a Senior Software Engineer with a clearance. I guess they have to pay for all the shiny buildings with below market pay. The recruiter was also very unprofessional and unresponsive. She could not be reached on the phone, would not return calls and took several days to respond to emails.
