Are you scheduled for software engineering interviews anytime soon? Do you wish to ace your interview to get that dream software engineering job? If your answer is yes, then you have come to the right place where you will get the information that will help you prepare well ahead of time.
Software engineering interviews can consist of multiple rounds. Algorithms and data structures are two crucial areas that employers could assess. Therefore, it should come as no surprise that honing your data structures and algorithms (DSA) knowledge is essential if you want to ace technical interviews.
Luckily, there are several websites that you can practice so that you can have a grasp of DSA. These websites become some of the greatest resources to use for coding challenges to hone your skills with data structures and algorithms. In this article, we have compiled a list of websites that you can practice data structure and algorithm coding tests before your interview.
Best Sites To Practice Data Structure & Algorithm Tests
Below is a list of websites that you can practice data structure and algorithm coding tests before your interview:
1. Leetcode.com
One of the greatest resources for getting ready for technical interviews is LeetCode. It covers a wide range of topics, from basic to complex data structures and algorithms, and is jam-packed with puzzles that you can solve.
If you’re just getting started, you can use the crash course on the platform to learn the fundamentals and get the self-assurance and abilities needed to begin problem-solving. Additionally, the platform offers editorial fixes for issues, highlighting the most effective course of action when you’re stuck.
2. Hackerearth.com
You can find practice sections covering data structures, algorithms, interview prep, mathematics, basic programming on HackerEarth. There are more than 350 issues in the algorithms area, compared to around a thousand problems in the algorithm section. You will be required to choose the languages you use after registering. Nevertheless, you can go through the problems in any language.
3. Techiedelight.com
There are about 600 issues on Techie Delight’s platform. This website is free to use and does not require account creation, in contrast to the majority of the expert websites on our list. The first issue is there for you to tackle when you visit the website. To obtain the most out of the website, we advise use the available filters. To see problems pertaining to data structures or algorithms, use the category and tags filter.
4. Interviewbit.com
Another good resource for DSA practice is InterviewBit, which has over 600 issues on the platform. It groups questions based on a variety of criteria, such as themes, firms, and degree of difficulty. Use the topic filter to delve further into the topics presented by particular sub-domains under algorithms or data structures for DSA practice. InterviewBit goes above and above by incorporating a Hints tab when you navigate to a question’s tab.
5. Codility.com
Codility is devoted to assisting businesses in hiring software developers. However, it also provides a training portion in addition to that. Although the app offers a variety of classes, it is far less extensive than the other three websites on my list. Challenges, lessons, and exercises are the three categories into which Codility separates its training.
6. Codewars.com
Codewars is not as intuitive. Although the tasks appear a little haphazard, you can use its filters to limit the presentation of challenges to those that are DSA-related. By choosing the Data Structures tag, you may observe data structures, and by choosing the Algorithmics tag, the same information is displayed.
7. Hackerrank.com
HackerRank is another reliable resource for honing your DSA techniques. It covers a wide range of subjects and languages, but the sections devoted to data structures and algorithmic issues are the most crucial. The coding challenges are categorized by difficulty level (Easy, Medium, and Hard), same like in LeetCode.
Conclusion
The seven websites listed above are the best you can choose from, if you want to ace your interview. All you need to do is decide which one of the sites meets your needs and head straight too begin your practice. Good luck!
