How the Quant Interview Preparation App Works

This little tool will assist you in preparing for a quantitative interview. It will ask you questions based on your current skill level and gradually increase the difficulty while you improve. To assess the difficulty of a question, we used the ELO rating system (used mainly in chess). In a nutshell, it works as follows.

• If you answer a question correctly, your ELO score increases, and the question ELO score decreases.
• If you answer a question incorrectly, your ELO score decreases, increasing the question ELO score.
• The degree to which ELO scores change depends on the initial difference. If you answer a relatively easy question correctly, your score will increase but in a smaller amount.
