Avantages
Well paid up until 2-3 year mark, which you are on a constant salary increase (above inflation) regardless of performance. If you are a high performer, you will receive an even greater salary increase, but regardless of performance, your salary will increase. Very competitive starting salary. You join in Graduate groups, so have an immediate peer network. Hampshire has a low cost of living vs London. Good compensation in terms of BUPA, Final Salary Pension Option for technical or managerial opportunities if an Engineer.
Inconvénients
Little development other than the mandatory soft skills training. Exxon training is not recognised by future employers. Very little work life balance support for employees - expect to eat at your desk, many people "burnt out"/long term sick. After about year 3, your salary will not be competitive against your peers in other industries / companies. Compensation package set up to benefit long term careers which is no longer guaranteed to the younger generation. "Global company" = America-centric. Very limited assignments abroad in recent years due to cost cutting. Many departments facing redundancies in recent months. Limited length of career if you are not an Engineer.
