The interview process was well-organized and supportive. First, I had a 45-minute one-on-one interview with my direct supervisor. After that, I received a writing assignment to complete within a few days. The team informed me in advance before sending the assignment, which helped me plan my schedule. In the next round, I had a 60-minute team interview with two team members. Both interviews were conducted in a very supportive atmosphere. The interviewer asked thoughtful questions and gave me time to think before answering. The questions were closely related to the internship tasks, including literature reviews, how to critically assess scientific evidence, global health work experience, research experience, and typical questions such as self-introduction and reasons for applying. They also asked follow-up questions to better understand my answers. My advice is to answer difficult questions step by step so the interviewers can understand how you think through problems logically. It is also helpful to have some background knowledge in cost-effectiveness, public health, literature reviews, and evidence-based decision-making.
