my first job was in a well-established company where the division of labour was very clear . i do not have more chances to enrich my experience . then i got an opportunity to really broaden my experience with a new company that was starting up , but unfortunately , they closed their service in three months ' time . i have worked in my present company for a considerable length of time and enjoy the job i am doing now , but i think i have accumulated enough experience to take up more challenging post in a much larger and diversified company where i could make solid contribution .
