I worked at Mattson Resources full-time (More than 3 years)
They put the customer 1st. They have deep relationships and trust from their clients.
It is a privately ran company that may not make the best decisions for infrastructure the 1st time, so things that could be implemented when 1st suggested tend to follow 6 months to a years later. Also company has unique culture on time keeping no matter how much OT you do, some would call it micromanagement, but you can get used to it.
I applied through a recruiter. I interviewed at Mattson Resources (Orange, CA).
Quite cordial with the recruiter. We were both military veterans so we spent most of our time comparing my military experience to align me with an organization. Once we got those particulars out the way, we continued to search for opportunities that would best fit my needs.
