Work on projects that produce something that solves one of my existing problems.

Never put a thing on your CV that you don't actually know. I've seen many people put a lot of languages that they don't really know, just to impress the interviewer and get rejected.

Java: I'm the complete OOP Language

C: I'm used in most of the places

Python: I am the simplest language that can do wonders...

Assembly level Language: At last you all have to come to me. So all of you STFU.

Using "%" as modulus operator rather than using it for percentages.
