Thesis and research-internship interviews
One entry per lab or group: your interests, a possible problem, why this lab, relevant papers, feasibility, supervision expectations and the prior work you will explain.
There is no standard academic interview loop
Labs differ widely: some hold an informal conversation, some ask about a paper, some include a coding or math exercise. Ask the supervisor or lab what to expect. The topic Research internship and Master's thesis interview preparation has a preparation checklist and question bank.
