How many coding questions in 1 hour interview?

In a typical 1-hour coding interview at Amazon, you can expect to be asked to solve 1 to 2 coding questions. The number depends on the complexity of the questions and the time you take to explain and implement your solutions.

Breakdown:

1. 1 Complex Question: Sometimes, you might receive a more complex problem that takes the entire hour. In this case, the interviewer will focus on how you approach, solve, and optimize the problem.

2. 2 Medium or Simple Questions: In other cases, you might get 2 medium-level questions or a mix of an easy and a more challenging problem. This scenario tests both your speed and problem-solving skills across different levels of difficulty.

What Interviewers Look For:

• Problem-Solving Approach: How well you break down the problem and explain your thought process.
• Code Quality: Your ability to write clean, efficient, and correct code.
• Optimization: Ability to improve time and space complexity, if necessary.
• Communication: Explaining your approach clearly and being open to feedback and improvements.
