Coding and design are not too difficult, as long as you're correctly prepared, and there are countless online resources for this. However, plan some time ahead to prepare the presentation and technical background interviews. Make sure to choose projects: - that you know enough to go in-depth technically - that are recent enough so you can answer questions without having to dig in your memories too much - that have a relatable tech stack, so that the interviewer can easily find relevant questions. One of the projects I chose didn't meet any of those criteria, and I did have a hard time keeping the interviewer engaged. I still passed, but in hindsight, I would choose something different.
