Questions In Interview

Interview Questions: How much would you charge to wash all the windows in New York City?



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

This is a trick question with a simple answer. Note there is nothing stated in the question about how many windows there are in New York City (which most people will try to answer) but how much you would charge.

You can rationalize our answer by saying what it would cost you to wash windows per hour.

If your hourly rate is $100 and assume you can wash 10 windows in a hour, then it would be $10 per window.

Note: For this problem solving job interview question, there is an actual logical answer, however the interviewer will want to evaluate your thinking process.  In answering the interview question, the lead up to your answer will be just as important as the actual answer itself.
