Interview Preparation Tips

Interview preparation tips for other job seekers - Amazon just want to see whether you have good problem-solving skills. If you show them, you are in.

Do DSA religiously from the beginning. Use GFG, Leetcode, InterviewBit, and Youtube. These are more than enough. Doing Competitive Programing is very helpful.

For frequently asked questions: Make sure you know the best approaches and edge cases, and write the whole code instead of just reading the solutions.

Start from brute force and keep on optimizing when asked, in order to show you haven’t already done the question before.

Speak while coding or thinking.

Repeat the question how you have understood it.

Find edge cases

Use STAR method for behavioral questions.
