Question regarding LLD round for SDE -2 position

After we do the class design, In case the interviewer asks to write working code of let's say BookMyShow or Splitwise, etc

Are we expected to write it in plain java, or we can create a Spring Boot app and use libraries like lombok ?

Because writing getter setter and constructors for all classes takes a lot of time

And completing the the whole interview starting from requirement gathering to class design to writing working code feels very challenging to me withing 1.5- 2 hours.

So how to approach this. Can some please share thier experience and approach?
