咁好睇你目標同埋本身有幾多internship experience喇，如果話本身真係aim grad時做big 4 advisory，咁一定衝啦。

Seems like a great opportunity wo! I guess the 2 most hindering factor should be: either (1) you may want to graduate asap for earning money (maybe due to family financial background), or (2) it is totally sth you don't want to do upon graduation. I would say in general a position in Big4 Advisory may enhance your opportunity to be hired by banks / financial institutions (FIs) or the industry in which the client project(s) you will be working. Or at least, you stand quite a good chance of gaining a return offer!
