Hiring manager 问了这个问题:
When is it ok to say, "I don't know"? When is it not ok?
我觉得对内部的时候可以说，对客户时不能直接说，而要说"我们可以去查/去test/去研究
"blablabla。
但我对这个答案不是很满意，不知各位前辈有何看法？
ps. 问题是透过email问的，我还没回复。

老板:你待会几点下班? I don't know, as a matter of fact,

I don't even know what "下班" mean. Sir.

回他I don't know试试

like now, when you ask me such a stupid question

这是个好问题 认真思考对你日后助益很多

It depends...

手下对老板真的最后不要说

1楼XDDDD

第一题:now, 第二题:now

You can say I dont know when someone criticize sth. Dont say I dont know when you report to customer or ur boss:)

尽量不说，因为是句废话。
