Jump Business Development interview questions

Interviewers were friendly and listened intently to my answers to their questions. However, all interviews were scheduled on the day of and I never got a firm date & time in advance. All three interviews were constantly cancelled and/or pushed back. Once I did get a certain time for a call, they often called 30-45 minutes later than that scheduled time. The offer was only 250EUR/ month to cover my costs (international flight, rent, food, etc.) which would have barely scratched the surface. Essentially they want unpaid or grossly underpaid interns. Overall, it was a very unprofessional experience.
