I would recommend learning the basic accounting before you start the job, but you will not need that for the interview preparation. Also, the case is a very simplified business situation and the accounting concepts are very often neglected. Here is a list of things you will need to know (and you can google them one by one since it is really short):

  • Profitability calculations (Operating profit, net profit, cost structure, etc)
  • Profit / breakeven formula
  • Interest rates calculations
  • Compound margin
  • NPV using the Rule of 72, Perpetuity
  • CAGR using the Rule of 72

Let me just throw some key words of financial terms at you which you should very familiar with: revenues, cost, profit, ROI, payback period, COGS, CAGR, NPV, balance sheet, income statement. Important frameworks/concepts are: profitability, 4 Ps, 3 Cs, Porter 5 forces, Breakeven, SWOT, PLC. I think you can find most important information on the bootcamp part here. What I did is go through that and if I had trouble with one particular thing I googled it and there are many free sources that are really helpful. I haven’t studied with a book, so I can’t recommend you one, sorry. Hope this still helps!
