Stuart is a computer science student who has an interview with Google but does not have time in his busy schedule to properly prepare. Normally, Stuart stays up late cramming Leetcode questions and feels unprepared in his interviews. He wants to make use of his in-between time, like when waiting for class or on the bus, to look up interview questions and company information online to better prepare. The document proposes developing an app called Code Hop that would allow students like Stuart to practice coding interview questions during their spare in-between moments to help feel more prepared for technical interviews.
