Well... It depends if you are doing the sales or working on site in the petro-plant... If you are doing sales then itz a great job to be in.. Aircon condition.. Long sleeve shirt.. Only have to worry about hitting your sales target... But if you are actually working in the plant doing site operations and maintenance.. Then not so good lah.. You'll be likely inhaling poisonous fumes 24/7 and face with potential work hazards such explosion, fire or other physical injury due to work accidents...
