Stewart and Stevenson provided me an opportunity to become part of the oil and gas industry. I came from a sweatshop environment in Central Florida and was seeking a new opportunity. I moved from sunny Florida to Texas to work in the most essential industry in the country. Stewart and Stevenson actually offered me $5k more than I requested.
The work environment was pretty laid back.
Production personnel were easy to work with and treated you with respect. For the most part, that applied to management as well.
From my standpoint, tasks were well defined and processes were fairly well documented. The company had a very good engineering change system and took full advantage of available software to process changes and new designs.
Due to an impending slowdown in the fracking industry, I elected to move, but if that didn't occur, I would have likely stayed there.
The only con was that designers were given free reign to walk over engineers at times. Most of the time that works, but it creates a climate of overt hostility at times.
