Difficult. Also depends on your class of honours, your degree course and also the job you're applying. But so far, I haven't met any SIM-UOL fresh grads that got into DXO. Probably more chances if you get in after a few years work exp. private uni grads who sign on also get less salary and slower promotion(after CPT rank) than their local uni counterparts. I'd advise you to work around 3-5 years and try to apply again.
