First you have to register on Lockheed’s website and upload your resume and cover letter. Then you can apply for whatever job you want that you feel you qualify for.
What happens next, if anything, is a recruiter will call you for an interview at the local recruiting center. At the interview you will most likely be given a presentation about Lockheed Martin before your interview which will talk the company’s products, benefits, and community relations. Then you will most likely go into a group interview consisting of 2 or more managers. The interview will probably not be very structured. They may ask you why Lockheed Martin and about things on your resume. The interview will last about 30 minutes. The interview is very laid back and the managers are very nice and receptive. After the interview you will be asked to give an exit interview where they will ask you question about your current job, why you want to get a new job, salary requirements, and other companies you maybe interviewing with. This part of the process will take about 15 minutes. The whole process will take about an hour or two.
After your interview day it will be on average a month before you hear anything from your recruiter about the position. Overall a good experience, but the unstructured nature of the interview makes it difficult to prepare for. My suggestion would be to have a good statement about yourself prepared and a good reason for choosing Lockheed. Also, be familiar with the job description that is listed because that will give you a hint as to the types of questions they may ask or you can ask them about.
