Drum is a very good company with huge knowledge within the maritime industry and other sectors within security. They have had a few rocky incidents over the last year or so with below par individuals showing there true colours on transits and project work, these colours nearly lost DC project work!.
I take it your going for an interview within maritime work, if this is the case then my best advice to you is know your industry that your going into, know the basic SOP's of what tends to happen and the BMP4 is always i good heads up for the none maritime individual.
To many lads are just rocking up and expecting a job......again try to gain as much info about the role you want to undertake, do some history on the company your working for and at the end of the day answer all questions truthfully and with conviction, if you don't know an answer to one of there questions because of lack of experience then say, as everyone has to start someplace if its because you haven't bothered your ass and just cuffing it then hopefully you will be shown the door!.
Anyway Dc is a very good company with a great deal of work for individuals if they want it, theres many different contacts so it really is down to you if offered a job, good luck
