Pros
Uness you work in a production environment, like Claims or Underwriting, you have an awesome work/life balance. State Farm gives their employees great benefits. A 401(k) AND a pension. Dental, Vision, Life, Health, Tuition Reimbursement, adoption assistance, and others that just aren't on the top of my mind at the moment. Excellent opportunity for advancement, career development.
Cons
If you work in a call center for State Farm, you have a very different experience. You still have great benefits. Even if you only work part-time, you still get paid time off, health, life, vision, dental, tuition reimbursement - the works. However, your work/life balance is significantly degraded in comparison to other positions in the company. The work also can get very mundane and boring. Still a great company, and really still good jobs, just not as good as the rest of the company enjoys.
