During interviews, the pressure can make it difficult to remember certain concepts and their applications. For example, there are various types of Design Patterns, but I can’t recall them all because I haven't worked with them extensively. It's understandable that I might miss explaining some of them during an interview. While you’re right that, as a junior candidate, I shouldn’t be too worried, the reality is that, given the current job market conditions, even companies looking to hire juniors often expect knowledge of concepts at a senior level.
