Interview Preparation Tips
Tip 1 : Practice regularly, meaning once you have covered all the topics, revisit them every week, and solve 3-5 questions.
Tip 2 : Use the Feynman technique. Explain your approach towards solving the problem to someone, or better yet, note it down so that when you revisit that question, the explanation is handy.
Tip 3 : Do 1 project, preferably a full-stack one including a database. This would provide some material for discussion, and be through with each aspect of the project.
Tip 1 : Keep the resume to one page and put info that is directly related to the role applied.
Tip 2 : In the projects section, keep a maximum of 3 projects, but ensure that at least one of them is hosted/live that can be shown to the interviewer.
