Preparation Tip

Tip 1: The key thing that played a major role in getting the internship was practicing problems daily on various coding platforms. One should prioritize solving Medium & Hard difficulty level problems.
Tip 2: Try to get really good at hierarchical Data Structures (Graphs, Trees) & various algorithms based on them, as they are commonly asked in big tech companies. 
Tip 3: Should have at least 2 projects and it would be a plus if that project has some application in real life, but it's not necessary. And the biggest tip for getting placed into Amazon would be - 'Be familiar with Amazon Leadership Principle'. There are 14 Amazon LP in total and they can be found easily online.

Tip 1: Do not lie about anything on your resume
Tip 2: Just keep it clean and elegant, E.g. as it would not make an impact if you won some competition at the school level (It would just consume the precious space)
Tip 3: Mention the projects that you have worked on along with the tools & technologies
