Tip
Tip

Tip 1 : Here I would like to advise practicing many questions on data structures, DBMS and algorithms as you can because it is the question practice that would help you in building your concepts strong. I practiced a lot of questions on Interview from all modules of data structures and algorithms because there you can find the recent interview questions that you should know. It is the main crux of any interview
Tip 2 : Go through Leetcode in details as it has a good variety of questions sorted on topic wise difficulty level where you can try to solve at least 40 questions for each data structure, DBMS and algorithm. Regularly participate in the contests happening normally on weekly basis there so that you could know about your weak areas to improve. This will boost your confidence.
Tip 3 : Also clear about some basic concepts of Operating systems and Databases along with coding , that would help in your interviews. One more thing is that do some good research about the company's goal and vision and be prepared to ask some company-related knowldege and queries that show your interest in the company. This shows your interest about the company

Resume Tip
Resume tip

Tip 1 : Your Resume should consist of as many as good skills, projects, and achievements and award won, if any. Projects would play a crucial part in your interview and you should have at least one most relevant and good project that shows how strong your concepts are in development. The good project gives you an added advantage.
Tip 2 : Never fake on your resume and like If you have worked upon some technology for the project part only and don't know the proper depth you could write basics only in your resume. If an misleading information is provided by you than you are going to caught as you will not be able to explain if any question is asked around that.
