SDE - 1

Tip 1 : You should be very fluent in each and every data structure that you have studied so that you are able to answer even the trickiest question by knowing the basics. This will happen only if you have tried enough questions on different platforms.
Tip 2 : Object Oriented Programming is the easiest and the most underrated concept. In every interview I have given so far, they have asked me the OOPs concepts. I have learnt and understood each and every basic concept of OOPs, primarily from the videos of Coding Ninjas which have polished my skill in this area and now I can answer any question of this topic. 
Tip 3 : The projects that you have done in your college life should be on your tips. You should know each and every little detail of it, and sometimes the interviewer may also ask what would happen if you changed some things in your project, so you should be clear with it's working and how would your project work after changing some specifications.

Tip 1 : Highlight your technical skills and write only the things from which you will be comfortable answering from.
Tip 2 : Try to maximize the number of technical achievements on the resume and minimize the extra curricular part.
