Interview Preparation Tips
- java basics theory
The interview was really easy I have to say that, but I could not clear it because I went more prepared for the coding part like write a program for this that, which they did not ask me literally nothing from coding. It's my fault I understand i should have prepared my theory better, I'm fresher I'm learning things but
I hope you will learn something from my mistakes and will succeed. I wish you all the very best for your interview and hope you will clear it. Thank you.
