3M Financial Analyst interview questions

3 parts to the interview: 1. Came in and asked me a question about why a 4 bedroom apartment cost less than a 3 bedroom apartment with the same SF in both. 2. Gave me a series of math questions, all of which could be done in your head, just how quickly you could rifle them off, was the goal. 3. Business Model was given you needed to ask as many questions as you could about it to form a business solution toward the problem.
