The first step after submitting an application can be a phone or virtual interview. Companies may ask you typical behavioral interview questions, such as, “What are your greatest strengths?” or “Tell me about a time you failed.” or “When was a time you worked on a collaborative project?”
Academic and government postdocs, though, will be more similar to graduate school interviews. Research mentors will ask about your projects and publications. They may talk about their own work and ask your thoughts.
Before the interview, read the research group’s most recent publications in-depth. Create a list of questions you want to ask about the research as well as some future directions you see for these projects.
