That depends. You mentioned not having needed in your job, but did you maybe have some recreational fun with algorithms and data structures? If so, maybe you can pick up what's necessary in the given timeframe (although even then it's tight).

I'm a bit wary of your claim of "not needing algorithms" at all. You must have had some sense of e.g. avoiding accidentally quadratic solutions when building your data tools?

If it's something you disregarded entirely, maybe you should move that interview out.
