I worked at Lufkin Industries full-time (More than 8 years)
Great place to work, friendly colleagues, learning opportunities.
All changed when they got acquired by GE. All went south from that point.
Advice to Management
Promote the right people (especially on the abroad entities of the company) to help the company move forward.
I applied through college or university. The process took 4+ weeks. I interviewed at Lufkin Industries (Lufkin, TX) in April 2012.
First interview during a college visit was a panel interview. The second invitation was tour at Lufkin Industries followed by 30 minute interviews with several managers throughout the day. The brief interviews are generally just to make sure you will fit in with the culture.
