Ventajas
OT pays well above average in my experience. Work life balance can be good but is 100% at the discretion of your immediate supervior.
Desventajas
You will be expected to churn out work at a ridiculous pace. Teams often feel undermanned and corporate bureaucracy in obtaining additional resources will impede progress. Often teams are missing critical resources so milestones and deadlines are consistently missed. CEO preaches that OT hires only the best and brightest but are unable to retain them because of atmosphere. Inter-department and inter-product work is thinly veiled finger pointing and true teamwork suffers because of it. Annual review process involves a capped number of reviews at each level of achievement so consistent high level work may only earn you an average rating because too many other people outperformed their expectations despite praise from reviewing supervisor.
