  • Before you register for Google Coding Jam, you must create a competitive profile at https://codingcompetitions.withgoogle.com/.
  • To participate in Google Code Jam, you need to sign up for each contest separately.
  • Only one contest profile is required to register for the competition.
  • Make sure all the information you provide during registration is accurate, complete, and in English.

Structure of Google Code Jam contest

Let us have a sneak peek at the structure of the esteemed contest. Google Code Jam covers a few rounds followed by the Code Jam World finals. Each cycle presents challenging algorithmic problems. Contestants must win each of these first rounds, and in the end, a total of 25 coding wizards reach the final match to fight for the title of popular champion.

1. Qualification Round

This is the first and easiest round in Code Jam. Problems in this round are used to test whether a participant has basic knowledge of problem-solving or not. Contestants have to score a minimum qualifying point (within 27 hours) to clear this round and progress to the next stage. The difficulty of the questions in this round is similar to problems with basic or easy level difficulty in the GeeksforGeeks practice portal

2. Rounds 1a, 1b, and 1c

Got the minimum qualification points? Congrats! Now the next step is the Round 1 of Google Code Jam, and this is where the real competition begins. The main features of these rounds are:

  • There will be 3 sub-rounds in Round 1- 1a, 1b, and 1c.
  • You will only get 2:30 hours and there will be 3 problems that will be more difficult than those in the qualification round. 
  • In each round, the top 1500 competitors will enter the next round. 
  • You can participate in as many rounds as possible until you rank in the top 1500 in any of the sub-rounds.
  • You cannot participate in other sub-rounds if you achieve above 1500 rank in any one of rounds 1a, 1b, or 1c. 

You need to have some speed and a good grip on the DSA(Data structures and algorithms) to be able to solve all the problems. But to qualify, even solving 2 or 1.5 problems quickly is enough most of the time. 

To achieve this goal without breaking a sweat, you can resort to the following links to help you out:

3. Round 2

Once you are in the top 1500 of any sub-round of Round 1, you will make it successfully to the next round – Round 2, where there are only 4500 participants left. In this round, Google will filter out the top 1000 participants that will advance to the next round. Hence, this time, the problems will be really difficult.

You should have quick problem-solving skills and almost expert-level competitive programming skills. We highly recommended you practice hard-level problems as much as possible, along with your active competitive programming streak. Practice as much as you can, that must be the motto to clear Round 2. 

4. Round 3

As soon as you prove yourself to be one of the top 1000 participants in Round 2, you advance to the next round – Round 3, and you earn an exclusive limited-edition Google Code Jam T-shirt.

Round 3 is held online and the top 1000 participants compete for the top 25 positions to qualify for the World Finals and move to the last step to winning the tournament. 

5. World Finals Round

The World final round is the most complex and toughest round of all. In the finals, not only the top 25 participants are eligible for the last fight for the tournament title, but also the last year’s Google Code Jam Winner

So in the World Finals round, a total of 26 participants battle it out at the venue, and the best among the best wins the Google Code Jam winner title, along with a whopping $15,000 winning prize.

Preparation tips for Google Coding Jam

From the above information on the Code Jam, it is very clear that you will have to be the best among the best to clear and win the Google Code Jam title. So how do you prepare for Google Code Jam? 

Undoubtedly, the best way to make an ace is to have an effective and sustainable preparation strategy, with the best knowledge of Data Structures and Algorithms (DSA). But, just for you, we will break down the Code Jam preparation strategy in the upcoming points, to help you gain the most.

1. Learn any Programming language basics

Though the Code Jam competition is all about competitive programming, but to begin with, you need to have the basics clear of at least one of the Programming languages, such as:

  • The basic syntax,

  • Conditional statements, 
  • Loops, 
  • Functions, 
  • Input/Output, etc.

2. Practice Data Structures

The main purpose of using Data Structures is to reduce time and space complexities. An efficient data structure makes use of minimum memory space and takes the minimal possible time to execute, thereby allowing your code to pass all the provided constraints.

Make sure to cover the below mostly used Data Structures in computer science, to make a solid base for your Google Code Jam preparation:

3. Practice Algorithms

It is essential to have an algorithm that is both time and space-efficient and the best way to illuminate various kinds of issues is with the help of various kinds of algorithms. Once you have a grasp of Data Structures, it is highly recommended to practice various algorithmic techniques, from any of the below links:
