If the interview is structured in a way that overloads your short-term memory, which is often the case, you'll have problems remembering things from a long time ago. Ask someone questions about recent events for a few minutes, and they won't even be able to remember not only what they worked on in projects many years ago but also their grandfather's name. Everyone has this problem; it's just how memory works, and poorly structured interviews trigger this effect. A workaround is to prepare beforehand and keep a list of things to talk about nearby.

Another approach that can work is to give your memory a bit of time to adapt. For instance, if you're asked to share a story from the past and you don't have one prepared and can't recall anything, suggest starting by discussing your past in general. For example, list the projects you've worked on and briefly describe them. You will feel how, during this process, the ability to recall events returns.
