accepted to eindhoven

hello guys! i got accepted to eindhoven for my bachelors in chemical engineering! yoohoo!

i was wondering if completing your undergrad would be enough to work in your desired field in eindhoven, or is it common knowledge to 'need' your masters before (for context, i am an international student)?

another question i have is if i can work whilst doing my undergrad. ex. taking shifts at a diner, or would i have to be proficient in dutch?

i'm considering committing later on, but shifting from school to work is a big priority for me.
