Pros: flexible schedule, laid back environment
Cons: job security, unclear management
I actually enjoyed my tenure working for Trialon; but the important thing to keep in mind is that Trialon is a staffing company. At it's core, I worked for Delphi, and my communications with were with them almost exclusively. I was able to rise up the ranks very quickly, taking a coordinator role for a project that involved seven different customers. Managing the resources and staff for that was rewarding, and I learned a lot in my time there. I coordinated driving and data analysis for an active safety program, essentially the radar system that gives warnings in modern vehicles. I extracted requirements from clients, arranged them into test procedures, scheduled the execution of those procedures, then analyzed the results and presented them in either written reports or presentations. My co-workers were great, and I was able to form not only some long term friendships, but great business contacts from six different countries.
The pitfalls came in two different incarnations. First, we experienced a dichotomy of management; as the Delphi manager became less visible, our staffing manager would attempt to interject with his own ideas. The problem became that the ideas often conflicted, and were often made by individuals who couldn't explain what those he governed did. The second issue became that, while our work was generally respected highly from high level Delphi engineers, you realize at times that you are the low man on the proverbial totem pole. I can still honestly say I greatly enjoyed what I did, and learned a lot of management skills.
