Preparation Tip

Don’t create panic in any case in the interview , as even if you are not selected you will learn a lot from your interview experience and perform well in the future. Also I would recommend you Coding Ninjas as according to me it is a good platform to learn basic coding concepts and to practice coding.

Resume Tip

Write whatever you are sure about and have actually done that. CGPA plays a good role but not a complete role as it is just eligibility criteria for some companies. Have at least 1 or 2 good projects from which you know everything involved in the project.
