Desventajas
Long term - you are simply an employee number at the end of the day. The closer you get to retirement your ranking will drop and it will be convenient to let you go before reaching retirement. Worrying about your employment status every few years due to the industry. If they over extend in oil exploration, they apply the same layoff standard to all sides of the business no matter how profitable your team is. Highly recommend you avoid this corporation if you have a family and a good heart that truly cares about people. Moved all customer service jobs to Buenos Aires - does not care about employing USA - only cares about pennies on the dollar no matter where they can get it. Look at Shell and Chevron before ExxonMobil as they allow their employees to interview for other jobs in the company before laying them off. If you are looking for a sales position they are moving away from outside sales to support customers to save more $$.
