Strategy and Approach to Answering a Problem Solving Interview Question

If you get asked a problem solving question in an interview, remember that they are NOT looking for the RIGHT answer. They are evaluating the approach you use to think out and solve the problem. A strong candidate demonstrates the following:

  1. Evaluates and understand the scope of the problem
  2. Communicates assumptions
  3. Demonstrates quantitative analytical skills
  4. Answers the question that has been asked. You’d be surprised how many candidates get lost in the analysis and solve for a different question than what was asked.


How to answer this problem solving interview question used by many companies (e.g., Google, Microsoft, Amazon)

Find the centers of both the original birthday cake and the removed piece.  Cut the cake along the line connecting the two centers.  This line cuts the original cake and the removed pieces in two equal halves.
