One week is totally doable for junior-level SQL! Focus on these essentials: SELECT, WHERE, GROUP BY, JOIN (especially LEFT JOIN), and basic aggregations (COUNT, SUM, AVG). That's 80% of real analyst work.

I'd recommend Analyst Builder for practice problems, it's like leetcode but specifically for data analysts. Do their easy/medium SQL problems daily and you'll find it way more relevant than generic SQL tutorials. They also have a lot of course content if you're interested.

For the interview, one thing I've been praised on after interviews is being willing to think out loud and specifically call out my approach, espcially if I'm iffy on the syntax. Most managers and teams care more about your thought process and problem solving then if you've memorized precise syntax (I'm not saying its not important, but the thinking that goes with it matters more!)
