In my opinion, Persistence, Work Ethics, Loyalty, 
Truthfulness and Insatiable Curiosity are needed to be 
success in a job

In this job the very first personality trait that will come
into picture is to deliver the work in time and with the
best quality. Rest that comes into picture are ethics, that
are very important in handling a task. Also, i would like to
say that being a team player is very important to deliver
(here any evidence of you being a good team player should be
give).
