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.
LambdaTest is a cloud-based cross browser testing platform that helps enterprises run web automation tests at scale (through parallel testing).
Selenium Automation Grid and Cypress CLI on LambdaTest You can attain better browser coverage by running tests across 2,000+ different browsers, devices, and operating systems online. LambdaTest provides a secure, scalable, and reliable cloud-based Selenium Grid that helps run Selenium tests at a faster pace. The Cypress CLI on LambdaTest, helps you expand Cypress test coverage to 40+ browser versions across Windows and macOS platforms. Along with automation testing, you can also perform manual tests, visual UI tests, and real-time tests.
**LT Browser - Responsive Web Testing* Additionally, LambdaTest also offers complimentary access of LT browser - a path-breaking developer-oriented tool that helps assess the responsiveness of your website. LT Browser eases the task of mobile testing as responsive tests can run against 50+ different device resolutions. You can also create custom device (or viewports) and test localhost URL without any extensions (or tunnels).

Initially we were skeptical whether a cloud infrastructure would be able to give us the flexibility, speed and browser coverage we need for our agile sprints. But LambdaTest has been a complete value for money to us.
They usually get the latest browsers on-board under 2 weeks time and are never compromising the experience over legacy browsers at the same time. The machines are quick to load and we rely heavily over the Monday integration, it helps us share screenshots instantly among ourselves without having to be stuck in long email chains.
We have been using LambdaTest for around 8 months and it has been so far so good.
LambdaTest has made our testing process less tedious with automated parallel testing. Builds that took days to complete with in-house infrastructure were executed in a couple hours. Parallel testing has helped us with faster feedback loops to scale up our go to market efforts.
Having a global user base we have active traffic from varied locations and testing on multiple platforms and browsers is a continuous process for the team. The feature that stands out for us is geolocation testing, all you need to do is run the capabilities and test the website for the desired location. We use Azure Pipelines for CI/CD and LambdaTest extension for Azure has helped us get a seamless testing experience for our privately hosted projects. Thanks to that we are now able to easily ensure browser compatibility for all the changes before we move them to Prod. Kudos to the team!
Have been using Lambdatest for around 6 months now, and could say that it’s a useful testing tool for our team. Offering great combinations of browsers and operating systems for you to test on and most importantly there are many types of additional logs that come with each test which helps in debugging.. Glad to see the integration with Travis CI due to which we could optimally use this tool with our CI CD pipelines directly. We were able to effectively run TestNG and Selenium tests using their documentation and as an added advantage their support team is quick and helpful

Have you heard of codeforces.com, atcoder.jp, codechef.com, etc? Source: 7 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: 7 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: over 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: over 2 years ago
