How to Prepare for Google Kickstart 2021-a CodeJam Competition?


This is a competition organised around the world mostly for the Asia Pacific region to test the problem-solving abilities, data structures, and algorithms of a participant.

Organised by Google is quite renowned for a high level of problem difficulty but also with a lot of interesting problems to learn from.

This is also considered a hiring challenge by Google. It consists of 6 online rounds of algorithmic quizzes designed by Google engineers. Out of these rounds, the top participants are invited to google for further rounds of hiring.

Eligibility Criteria for Google Kickstart 2021

  • Generally, anyone who is older than 16 years of age at the time of registration is eligible to participate although you have to be 18 years or older to be contacted by a Google recruiter for subsequent rounds of interviews.
  • Moreover, it prohibits users from Crimea, Iran, North Korea, Quebec, Syria from participating in the competition.
  • All of these communications are maintained by Google through email and website.

Exam Pattern of Google Kickstart 2021

There will be several rounds each of 3 hours of algorithmic challenges throughout the year at separate times.

  • Each round does not need qualifications from previous rounds.
  • Each round consists of 4-5 problems to be solved.
  • The round schedules are given on the official site and registration is valid till 14th November.
  • You can get a detailed timeline and registration information via the link.

Previously Asked Questions in Google Kickstart 2021

Past problems are very useful in preparing for this exam. Those questions are based on some important topics I will be mentioning some important topics for this:

  • Number Theory
    • This includes basic number theory problems even starting from GCD, LCM, modulo operations, Fermat’s theorem, etc.
    • You can also follow some number theory problems from Coding Ninjas Course for learning in-depth about these concepts.
  • Greedy Algorithm
  • Binary Search
  • Dynamic Programming
  • Divide and Conquer
  • Hash tables, maps
  • Trees, BST, BIT, Trie
  • Bit masking algorithms
  • String matching algorithms like KMP, Rabin Karp, etc.
  • Graph algorithms like DFS, BFS, Dijkstra, Floyd Warshall, MST, etc.

You can refer to Coding Ninjas courses for the best in-depth explanations for understanding these concepts.

Prerequisites for Google Kickstart 2021

This includes strong skills in data structures and algorithms. Most of the problems will include:

Any popular language can be used for this as Google provides supports for Java, CPP, C, Python, Golang, JavaScript, etc, and many more.

Preparation Tips

Start with learning data structure and algorithm and keep practicing in various other platforms like CodeStudio, CodeChef, GFG, Codeforces, CodeJam, etc. which will help to improve problem-solving skills and get you habituated with online coding IDEs. Brush up some really important algorithms like greedy, dynamic programming, divide and conquer, shortest distance graphs, etc.

Get familiar with asymptotic time complexity notations. This will help you to analyse your current problem complexity and if that is slow then you have to think of a different or optimised algorithm.

It is always advised to practice past years’ kickstart competition which will help to get you an idea of types of problems. Personally, I will suggest aiming within 100 in the first few APAC tests which will improve your chances for interview shortlisting for Google.

Frequently Asked Questions

How is the score calculated in the contest?

Your score for a problem consists of a point total and a penalty time. The penalty time is partly determined by the number of penalty attempts. For every successful passes of verdict then for each such passes you get one score. There are no partial credits for passing some of the test cases.

What are the benefits of Google kickstart?
