If the recruitment during the university is successful, do you go directly to the unit for internship or continue to attend classes on campus for several months?

I have been there before, and the following views are for reference only.

Look at the actual situation:

First, ask the teachers in the department for advice. If the school agrees to go to the unit for internship, then go quickly, now or never, seize the opportunity;

Second, if the school doesn't agree, then talk to the employer about the actual situation.

It is so difficult to find a job now that the school generally agrees. They are all happy to give it away, as long as the unit wants it.
