Vantaggi
In San Antonio, one of the better employers in terms of salaries and benefits (certainly not the best in my opinion). Health and fitness is part of Valero culture. It's implicitly understood that all the employees will be out for a workout during lunch hours. Post lunch meetings are usually scheduled keeping this in mind. It offers great work life balance. It has relaxed the dressing code in recent years. The IT team is of a medium size. Almost everyone is busy with one project after another. Valero is a big SAP client. It leverages a lot out from SAP. There is lot of interesting work, but it does have some mundane stuff that needs to be taken care of as well. Valero is a safe company to work with. Its business model is conservative and mitigates risk. Moreover it is the industry leader in the refining field. It does not lay off employees.
Svantaggi
Valero is a conservative company. They offer very less vacation time. Work hours flexibility is less. Work-from-home option is not available. The pay (salary and benefits) may not seem attractive if compared to an IT organization. There can be a bit of micro-management.
