I had a skype interview for an unpaid position within IPA. The interview lasted 30 minutes and not any minute more. They asked me to introduce myself and explain why I chose IPA, and about data analysis and management projects I had done in the past. Then some questions on team working and how I would deal with situations in a developing country and more precise questions about my logistical skills. From the feeling I had they were looking for someone they couldn't pay (at all) to do the boring logistic job of the data collection process. Did not feel like there was anything to learn as an "intern" there. Such institutions should stop the 21th century of unpaid internship that recreate the inequalities of class.
