how old are you? honestly CS dont really care about your experience outside, they value their fresh grad scholars more. i think you are realistically a mx13, but if you have connection and ace your interview, got maybe 10% chance for a mx12.

my advice, sign on home team. your profile will easily be in the top 5% of the officers they take in, easy promotion for you as long you dont screw up like the former SCDF or CNB directors.
