Tip 1 : I would suggest practicing as many questions on data structures 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 InterviewBit and completed all modules of data structures and algorithms because there you can find the recent interview questions that you should know.
Tip 2 : If you have time for your interviews, I would recommend going through Leetcode as it has a good variety of questions sorted on topic wise difficulty level where you can try to solve at least 20-30 questions for each data structure and algorithm. Moreover, you should regularly participate in the weekly contests happening there so that you could know about your weak areas to improve.
Tip 3 : Along with coding you should be clear about some basic concepts of Operating systems and Databases 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 queries that show your interest in the company.
