如果我不清楚收信人是誰, 又要寄履歷表到公司, 應該打 Dear 什麼?

call間公司, 接去HR, 直接問佢你個post的負責同事叫乜名, 或個HR Manager叫乜名. 咁最有誠意, 表示你唔知就會問! 再好似下面咁開頭:
XYZ Ltd.
1 Connaught Place
Central
Hong Kong
Attn.: Ms. Anna Wong - HR Manager (or) Ms. Tweety Lee - HR Officer
Dear Ms. Wong,
........

或者可以打:

Dear Advertiser,

Dear Personnel Manager,

Dear Sir / Madam, 就是基本信件開頭語.

Dear Sirs/Madams ,

Dear Sir / Madam
