回复：多谢大家的回复

好在第一个OFFER虽然要一周内签字,可上班时间要到7月6号.
-- nice, so you will have enough time to reject it later.
-- even you can quit job after you start.

老土说可以告诉第二家我手上有个OFFER,那我能告诉第一家我有个面试,要等结果和他们的比较么? 能用这个理由推迟签字么?
-- Not necessarily to do it.
-- I will not do it.
-- Because that's not their business.
-- I do not need report to them.
Thanks!
