原句,to be involved.不是很恰当．
改句,It 's a run-on sentence.
应该 Keep the sentence neat and sweet!
My goal is to join the finance field of an international company,which can help broaden my view.
Why?
The word "current" is not necessary.When you are making your present statement,without a doubt it would be current.So the word current is an extra because It is not important here.
"join" and "join in " would mean the same.
"in an international company in finance field" Try to use different words to make your reader excited.not "in.in."
It' also hard to understand.we want to use ".of."
"develop myself" is an unclear statement.
