I am a MSc student about to graduate in Amsterdam - domain is Data science (but i have a BSc in CS) - how would I approach a company about part-time work? Most positions are advertised as full-time, do I just apply for them and then if they chose me, mention that I only would like to work part-time? I feel like if i mention it too early in the hiring process they may actually chose a candidate that is able to work full-time.
