Same as General Dynamics.
Both, L-3 and General Dynamics are in a different business and product lines than HP/Agilent Tech., therefore, the first weeks at work was most involved to learn the products, internal and external partners, products and how they were built (actually sitting on the line with the tech and learn how the products were built).
The management and workplace culture similar to General Dynamic.
Hardest part:Assurance of supply from single sourced suppliers. The suppliers were manufacturing certain parts only for L-3 and no one else!
Most enjoyable parts: Accomplishment, teamwork, and positive results.
