The technical face-to-face interview round is the most crucial in the entire interview process. You should be well-versed in computer science fundamentals such as OOPS, DBMS, CN, OS and be able to communicate them clearly to the interviewer. Programming language knowledge is required. Make sure you're familiar with at least one programming language. It is not necessary for you to be fluent in all programming languages, but you should have sufficient experience with at least one of them, such as C++, Java, or Python. There is a considerable chance that you may be asked to write a code on pen and paper. Problem-solving skills will also be checked by the interviewer. Knowledge of the most recent technological developments is an added advantage. You should have a fundamental awareness of contemporary technology trends, such as artificial intelligence (AI), big data, and so on. You'll be asked questions about your previous projects and job experiences, such as what you did, what technology you utilized, what you developed, and how successful you were, among other things.
