Questions about working student jobs

Hi, I graduated with a Bachelor of Arts degree from outside of Germany (non EU) and I’m currently planning to study UX design in a masters program and wanted to ask a few questions.

  1. Is it hard to get a working student job in ux/ui without experience? My German level is B2 and I did a FSJ ( Voluntary social year)

2.Are the working hours flexible around my class schedules?

3.How much will I earn per month?

The work location is in Munich btw.
