Good that you're building data skills. But I think you're optimizing for the wrong thing.
Healthcare firms don't reject candidates for not knowing Power BI. They reject them for not being able to structure a problem and drive to an answer under pressure. Tools you learn on the job. The thinking you need before you walk in.
On technical skills, in order of real usefulness:
- Excel. Master this first. You'll live in it more than any other tool, and most candidates skip it to chase fancier things.
- Power BI or Tableau. One is enough. You're already on Power BI, so finish it and move on.
- SQL. Useful for pulling and cleaning data. Worth a few weekends.
Plus basic healthcare fluency. Know the players, payers, providers, pharma, medtech, and how money flows in the system.
But here's the real point. If you have 10 hours a week, put 7 into case prep and 3 into everything else. Technical skills are table stakes. The case interview is where offers are won and lost.
