I worked at Continental full-time (More than 10 years)
Truly outstanding and innovative employer. Technology leader or co-leader in many Automotive fields. Opportunities to be involved in a huge variety of different automotive technologies. Work life balance very good in many departments, though this varies with Manager and department. Workload generally manageable.
Very limited promotion opportunities if you are looking to move upwards and continue a career. This has forced many 10+ year employees to leave to seek new challenges. Management spends insufficient effort to provide a stimulating environment for higher potential employees. They will continue to lose talent that should not depart the company.
Advice to Management
The Grade 13 "ceiling" is hindering growth of too many Grade "12" employees, forcing many to leave. Mgt needs to get much more creative to stimulate high potential employees either via job rotations, temporary (3-6 month) overseas assignments, etc. Continental is a great environment to work in...but Managers are getting clogged up at the Grade 12 level with no place to go. (Hint: Don't let low employee attrition "statistics" lead you to believe that all is good. There is a festering problem among Grade 12s that could eventually cause an outflow of great talent.)
I applied through a staffing agency. The process took 2+ months. I interviewed at Continental (Seguin, TX).
You will already have worked for their staffing Co. When they decide you are ready to be hired on, they will have you fill out another app, have an interview with your boss, and take a really simple math test. Then, you have to take a drug test (pee & hair) and done.
