What is a good way to prepare for Google Code Jam?

To prepare for Google code jam, first of all you need to understand the whole structure of Code Jam. So, I will answer your question with respect to each round.

Qualification Round

This is the most easiest round in code jam as far as I can see from previous year questions. Problems in this round are used to check whether participant have basic knowledge of problem solving or not. Minimum cutoff required to pass this round is 30 points in 2020 code jam. Difficulty of questions in this round is similar to codeforces Div 2 A B C and you can easily solve these problems with some efforts even if you are just a beginner. This round will be for 27 hours this year.

Round 1a, 1b and 1c

This is where the real competition begins. You will only get 2:30 hours and there will be 3 problems which will much more difficult than those in qualification round. From each round top 1500 rankers will qualify for next round. Note that you cannot take part in 1b or 1c if you were in top 1500 in 1a. You need to have some speed and a good grasp over DSA to be able to solve all the problems. But to qualify, even solving 2 problems or 1.5 problems quickly is enough for most of the time. Practice codeforces Div 2 C D and some E problems to get a good idea of the problems you are going to face. Also solve previous year codejam questions.

Round 2

Now there are only 4500 participants left. This time problems will be really tough. You can expect this round to be similar to codeforces Div 1. Don't forget that top 1000 coders from the world are also taking part ( like Div 1 guys on codeforces, 7 star on codechef ). Hence, you should have really speed and problem solving skills. I will advice you to take part in codeforces Div 1 contest as much as possible. Practice as much as you can and revise your DSA concepts. Only top 1000 guys will move to next round.

Round 3

You don't need any advice if you have come this far. I will just say practice, practice and practice because only top 25 will move to next round.

Final onsite round

You will be in the same room as the tourist himself. So, you know who you are, what you are doing and why you are doing. I will just wish you best of luck.

Summary :-

Practice practice and Practice!

Keep increasing difficulty of the problems you solve

Best of luck guys and see you in code jam 2020.
