I have been working at Martin Marietta Materials full-time (More than 3 years)
The people employed at Martin Marietta are among the best in the industry! Safety is truly the most important thing from Ward Nye down to every employee. The benefits are out of this world: pension, 401(k) contributions, tuition reimbursement, scholarship opportunities for your children, good pay, excellent health/dental/vision. Growth opportunities abound.
There aren't cons. I left for a bit and came running back!
Advice to Management
Make sure to keep all employees as your focus as you do! Safety should remain paramount!
I applied online. The process took 5+ weeks. I interviewed at Martin Marietta Materials in April 2017.
Phone interview, in person dinner meeting, site tour and observation , very relaxed paid for travel and extremely professional! I was introduced to the entire staff, felt very welcome and even more excited to begin working!
