For the past five years, I have been engaged as a correspondence clerk.

在三年，本人一直担任对外书信主稿。

I'm a clerk, but I've also had some experience as a secretary, including answering routine correspondence, taking phone calling and dealing with business for the boss.

我是一个职员，可我也有做秘书的经历，包括处理日常书信，接电话，处理一些上司的业务。
