Preparation Tip

Tip 1 : Questions are asked on DSA, so practice questions and it is not the number of questions you practice, but how well you practice the questions. Prepare a notebook and write down the approach you follow. Make proper notes and maintain that notebook. Will help for quick revision.
Tip 2 : Conceptual questions are asked from topics other than DSA. So watching videos on youtube will not help. Read the book thoroughly to make yourself ready for interviews.
Tip 3 : ALWAYS read about the real-life examples of the concepts you read. This is often asked in interviews and you will definitely regret failing to answer this question.

Tip 1 : Having projects in resume will help you to give the direction to your interview, which increases the chances of selection.
Tip 2 : Add some achievements other than academics, it shows that you are a team player and increases the probability of getting shortlisted. BUT do not write anything that is not true or else, it will backfire.
