Changing Full-time Application into Internship Application

First, don't forget you can generally delay an interview if you need more practice time

Second, I feel like this would be a company/office dependent answer -> you probably should call HR and ask them directly.

FWIW, I am generally not a fan of delaying an application to get an extra degree just so "you can be more prepared". If you want something, go for it - today, not tomorrow*

* "go for it" still assumes you are properly prepared obviously, but that doesn't  take a full year of studying

Hi,

Agree with Guennael. It depends on the office and you should contact the HR directly

Best!
