Before （）for the job,you will be required to take a language

不一样的 before applying 在找工作前, be required 先发生
上次那个 having seen her 见过她之后,之前见过她 didn't know 后发生
not having seen her 之前没见过她 didn't know 后发生
如果是After applying for the job, 就和having applied一样了
having done 基本=after doing
比如having worked here for 10 years, he is experienced.
= after working here for 10 years
再问： 就是 上次那个having seen her 之前见过， 还不知道他长相是不对的。 这次这个是。 找工作之前的动作。 然后如果是申情工作之后，在培训就跟那个having done 一样了。
再答： 嗯，是的
