Interview preparation is something most people blow off. They know who they are so they don't need to prep right? Wrong! Being able to review your past projects and experiences will remind you of the important details that will make you shine. Everyone will have a generic project such as modeling weather with time-series. As an employer, I want to know what were the steps, what were your problems, and how did you solve them. Your process tells me a lot more about how you think, your personality (organized, team player, out of the box thinker), and your skills than your resume. Anyone can write, "Hard Worker," "Motivated," "R," "Python," and "Machine Learning" but only those who have greater depth can tell me important details. As an industry professional (and past student) I know which parts are challenging and I want to see if you actually did the project well or if you just checked the boxes for the assignment. A lot of students do the bare minimum and most interviewers will pick up on that.
To best prepare for an interview, find someone to talk to about your projects or write down the projects/experiences from your resume and then create a list of what you did, the problems you had, and how you solved them. As time passes you will forget a lot of the details so going back and thinking about the projects will make you look a lot smarter and more polished.
