“As humans, we have evolved to compete; it is in our genes, and we love to watch a competition.” – Peter Diamandis
If you are a coder, and you say you are one of the best coders out there, I would ask compared to whom? If you are to prove yourselves better, the primary need is to have someone who is less good than you. While you may feel that comparison simply increases restlessness; a healthy competition, can help you show your competence. This becomes necessary if you are on a lookout for a good employment opportunity as a coder. Coding competitions are a great option for this. A number of platforms or websites today are issuing such competitions. They are lucrative for participants, offering them a number of internships opportunities, scholarships, and even job opportunities.
Competitions are blessings in disguise and they do great in boosting confidence as well as skills. For a coder like you, who is thinking about making it big in this world, they are your answers. So, which are Competitive programming websites on which you can keep an eye – to participate, to win (or loose), but find some really great opportunities and improve your self-worth.
