Advice: Level 2 Viva took around 30-40 minutes for me. Please review the questions previously asked by this proctor, as he tends to ask similar ones. If you are still not satisfied, prepare all the questions in this sheet. Make sure you fully understand the code, including the syntax and how it works. The proctor is approachable and may offer assistance if you get stuck. If you are unsure about any topic, he will help you. The changes in the code will be something you have already implemented or similar to your previous implementations. Therefore, ensure that you are completely clear on the logic behind your code. Be patient and well-prepared. That’s all you need, along with a bit of luck.
