Interview Preparation Tips
Tip 1 : Have your basics storing rather than focusing on react or any other similar frameworks
Tip 2 : Practice DOM manipulation using JS as in the assignment round you'll have to code an assignment with your screen shared
Tip 3 : Practice advance JS concepts like prototyping, promises, etc.
Tip 4 : Study your projects thoroughly, what tech you used where and why
Tip 5 : Don't think that if you are unable to answer some output based questions or to code some question so you will not get selected. I myself have multiple wrong answers to tricky js output based questions but then the interviewer asks you to execute the question and explain why this has happened. If you are able to explain the correct reason for the answer you are good to go.
Tip 1 : Mention your best projects along with Tech stack used so the interviewer can see what all tech stack you have worked on
Tip 2 : Do not put false things on resume, as the interviewer will definitely ask cross questions and you will get tricked.
Tip 3 : Don't worry about the resume too much, you are the main focus of the interview and not the resume.
