Ventajas
There are very few pros with VSP, but your vacations will never be denied. The door is always opened and a great place to start an office career. (be careful, they call VSP "Hotel California, very hard to leave once you're in) 401k is fair. Dental is good and vision... come on you own a vision company give a little coverage...1 pair per year. Coverage is very limited to their brand and its subpar at best. Company Cafe's are great. Cake day once a month. Casual environment. Flexible work hours for some departments. EAP and you're going to need it.
Desventajas
Medical benefits provided "VERY" high deductible. The company contributes $300/$600 per yr to cover employees/family out of pocket expenses and but you pay $4000 deductible per employee and each family member, then your coverage kicks in. Wages are way below what other health companies in the area especially if you take into consideration the medical coverage. If you need the work experience VSP will do the trick but get in and get out as soon as possible.
