Google is an innovative company, solving daily life problems and giving unique solutions. Google HashCode is a competition where Google tests the practical daily-life problem-solving knowledge and skills of programming students and professionals.
It is a team-based competition, which means you’ll have to work and collaborate with other programmers and coders to ace in this competition. You may want to brush up on your existing knowledge and skills before taking part in the Google HashCode Competition as many experienced and expert professionals participate in it.
You can find many free and useful courses on programming languages on websites like Coding Ninjas that will help you excel in this competition.
This year due to the Covid-19 pandemic, the Google HashCode competition has gone virtual. There will be an Online Qualifications round first and only the top teams selected after this qualification round will be invited to participate in the virtual World Finals.
To participate in the Online Qualifications round, a participant must be at least 16 years of age, but the eligibility criteria for the World Final in terms of age are different. For the Google HashCode World Finals, the participant must have attained the age of a minimum of 18 years, plus they also should have attained the age of maturity in their country.
It is important to understand the exam pattern before going for an exam. Once you’ve registered for the Google HashCode competition online, you’ll receive access to the Judge System where you can join a hub, make a team, and practice and compete.
Your team will have to solve a programming problem within a given timeframe of four hours to pass the Online Qualifications. After you’ve succeeded in this round, you’ll appear for the virtual World Final where you’ll have to solve another optimisation problem as your new challenge and compete with the top teams.
