Good experience.
Pros
If you want automotive experience for parts and want to take advantage of the employee discount to fix your car, then perhaps it's the job for you. Depending on your background in automotive and whether you're ASE (Automotive Society of Engineers) Certified you may be given a bit of a jump on your salary.
Cons
Now it all depends on which store you're at but don't expect a solid schedule. Expect shifts to change every week and expect to be scheduled on weekends. If you're new you'll be put on the hot seat, you'll learn as you go. Also, if you're the red shirt closer (Customer Service Representative) expect to clean bathrooms and mop floors. Expect to stock items which sometimes can be EXTREMELY HEAVY! For example, Chrysler 300 brake rotors are no joke! Also, ALWAYS count your register BEFORE and AFTER your shift! Mistakes not made by you on your register can be blamed on you and you can be written up.
