What is your motivations in asking this question?

Or should all soldiers say "to protect the country" or all teachers to say " to inspire the next generation" to fit your agenda? What about those working in Mcdonalds or selling insurance. What are their motivations? A HDB officer, LTA staffer, MOE HR manager. what are their motivations?

To answer you if you are somewhat honestly curious,
DXO is just a job in which a point of time, seem like a logical choice. i dont think anyone grows up and dreams of being a DXO.
A suitable and stable job for those seeking work life balance, job security and somewhat with a purpose of contributing to national security.
