When preparing to answer backend technical interview questions, start by noting that one of the most important things an interviewer looks out for is your work style. Are you an independent worker? Are you creative? Do you work best within a team? What is your work philosophy?
They may not ask these questions directly, but even in the technical questions they ask, they expect the answers to be embedded with easily discernible clues to what it looks like to hire/work with you.
Therefore, you need to pay attention to not just your answers, but how you deliver them. Interviewers are not only interested in how well you can describe caching, CI/CD, architecture, or software scaling. They want to see how you integrate these skills and knowledge into your work. As such, feel free and confident to draw from a personal example of your own work that can buttress your points and your delivery.
