CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.

Are you sure, I got a link to a codingame.com assessment from block. Source: 10 months ago
This, and OP should practice handling the stress. Find a friend to do interviews with, or give yourself a timer, or whatever. codingame.com is a good alternative if you want to try dealing with a timer and don't want to be able to cheat. Source: 11 months ago
Just jumped to codingame.com and start (cant) solving puzzles. Source: 12 months ago
Personally, I like codingame.com (completely free unless you are an employer) - Their simple puzzles are great places to get an idea of how programming works and the kinds of problems they solve. I think the first puzzle I was able to solve as a beginner in a few days. Source: about 1 year ago
I believe it's possible to use rust in codingame.com. Is that ok for you? Source: about 1 year ago
Have you heard of codeforces.com, atcoder.jp, codechef.com, etc? Source: 5 months ago
Leetcode is good to learn basic algorithms because problem statements are usually straightforward. Competitive programming has much wider range of problems. Most popular sites for cp are codeforces.com , atcoder.jp, codechef.com . Source: 5 months ago
Learn Java with hands-on experience. I personally used codingbat.com a lot, but I've heard good things about codechef.com, which appears to even have a competitive option. Source: about 1 year ago
For practicing algorithms, use any of the freely available websites like https://hackerrank.com https://codechef.com https://projecteuler.net A structured set of practice problems are available at https://www.interviewbit.com/courses/programming/ Avoid https://geeksforgeeks.org because it has a ton of material but very poor quality control.

These all have sample problems to solve Hackerrank.com edabit.com codewars.com codechef.com and there are tons more. Best of luck to you. I am at about the same level myself. I really like these sites. Source: about 2 years ago
