The whole process had 4 rounds:

1. Aptitude and Essay.
2. Technical MCQs.
3. Technical Interview.
4. HR Interview.

Technical questions comprise basic concepts from your branch-related topics, plus basics of computer science (C, OOP, DBMS). You may also be asked to write basic programs like a palindrome check, reverse a number, or prime check. Questions will also depend on what you have mentioned in your resume; make sure that you have a proper understanding of the things you have mentioned. If you mention Java in your resume, questions will be asked from it as well, so if you are not confident, mention just one language (C or C++).

You will be asked to explain your B.Tech project also, so prepare an abstract description of it.

What is the finalize() method in it?
