郵件備份會很久,無需為此而發愁. 公司資源不要用, 包括電話和電郵.

During job hunting:
Don't leave office phone;
Don't use office email;
Don't tell current company name unless it is necessary;
Don't use current boss as reference;
Don't use people in current company as reference;
Don't say you are going to a interview when you ask time off;
Don't quit current before you get a solid offer in hand.

Thanks!
