Pros
Pretty good development programme. Diverse bunch of rotations enabling one to pick up every detail about oil trading. Flat organisation for most part in day-to-day business sense, easy to reach out to mid level management.
Cons
Poor programme management (no trader jobs at the end of the scheme even if you pass the programme) - so go into this expecting it to be a commercial scheme rather than trading scheme. Discriminatory practices between geographical regions - this is a western company and sadly that still means that London and Chicago call shots on everything. This means grads in western offices get better pay/ pay rises while grads in the east sometimes don't even get pay increments. Similarly, more trading jobs in the west at the end of the programme while east rarely hires. Management promises hold no worth - promises (mainly on jobs) are made and withdrawn arbitrarily citing seemingly ridiculous reasons. Definitely right place for someone who is very good at office politics and so-so at actual work. Poor bonuses - Expect bonuses that are inconsequential whilst on the trading scheme. Base pay in Singapore (and the pace of pay revision) is very suppressed compared to western offices contrary to what one might expect due to ordinary inflation pressures. Slow organisation - immense size means sometimes there is less work and more meetings but suspect this should be similar in every big organisation.
