Algorithms Interview Strategy for Google
Interviews in this topic usually test how clearly you can explain concepts, compare alternatives, and apply decisions to real systems. Treat each question as a mini case study instead of a one-line definition.
A practical structure that works well is: define the concept, explain when to use it, share one concrete example, and then mention one common mistake or limitation. This helps your answer feel complete and interview-ready.
Use this question list as a revision loop. Solve all questions once, mark weak areas, and then repeat only the weak questions until you can explain them confidently without reading notes.
