It is more important than ever to get ready for coding interviews, especially for tech companies that are very competitive, like Google, Amazon, Meta, and Microsoft. Using apps to help you prepare for interviews can give you an edge, save you time, and make you feel more confident. A lot of apps have mock interviews, coding challenges, and skill-based analytics all in one. In this guide, I will talk about the best seven apps for practicing coding interviews. I will also use high CPC keywords like “Ace the coding interview,” “online coding test,” and “coding interview preparation.”
1. LeetCode
One of the most well-known sites for preparing for coding interviews is LeetCode. It has a huge library of problems that are sorted by company, topic, and level of difficulty. LeetCode Premium gives you access to problems that top employers ask, which makes it easy to focus your study.
You can send in answers to each problem in a number of languages. You can also practice coding under pressure with timed contests on LeetCode. Users can talk about different approaches, look over solutions, and make their own study plans. LeetCode is an app you need if you want to take “online coding tests.”
2. HackerRank
Companies use HackerRank as a “online coding platform” to screen and interview candidates. The app talks about a lot of different things, like algorithms, databases, data structures, AI, and more.
HackerRank lets you take practice coding tests that are like real job interviews. You will find lessons, mock interview challenges, and interview packs for specific companies. They also have leaderboards, certificates, and role-based tracks that can help you “practice for coding interviews” in a more organized way. This is great whether you are interested in algorithms, SQL, or front-end work.
3. CodeSignal
CodeSignal is a clean, professional place to do “coding interviews online.” The Arcade section starts with basic topics like arrays and strings and then moves on to more advanced topics like system design and data structures.
You can take part in practice interviews and challenges with more than one round. Top tech companies trust the app’s “General Coding Assessment.” It shows you your rank in the US and around the world after each practice session, which is a big motivator.
4. CoderPad
CoderPad is made for “live coding interviews.” CoderPad lets you practice interviews with a real code editor and run your code in over 30 languages. Some companies use CoderPad for real interviews, so practicing here will help you feel less nervous during real interviews.
You can fix problems with replay, review past sessions, and learn how recruiters give feedback. CoderPad gives you a realistic coding environment to help you “Ace the coding interview” in group practice or private sessions.
5. AlgoExpert
AlgoExpert is made to help you get ready for a “coding interview.” It has more than 160 carefully chosen coding interview questions, each with a high-quality video explanation. Every problem has a breakdown of its space and time complexity, which helps you understand it better and improve your problem-solving skills.
Their professional interviewers will help you understand complicated data structures, dynamic programming, and system design one step at a time. AlgoExpert’s system design section is great for “system design interviews,” which are common for senior software engineering jobs.
6. Interviewing.io
Interviewing.io is a free site where you can have “mock coding interviews” with engineers from big tech companies. The practice is honest and low-stress because neither you nor your interviewer know who you are. After each interview, you get feedback on how well you wrote code, how well you communicated, and how well you used technology.
They also have live mock interviews where you can “practice coding interviews” and win prizes. This setting helps you feel more confident, respond better to feedback, and deal with nerves before a real interview.
7. Pramp
“Pair programming mock interviews” is what Pramp is all about. You can do live, timed interviews with other users through the app. You take turns being the interviewer and the interviewee, which makes the whole process better for both of you.
Pramp has coding interview questions, behavioral prompts, and tools for giving feedback. Like a real “online coding test,” practicing with real people—often strangers—makes you do things that are hard for you.
More Tips to Do Well in Your Coding Interview
– Do not skip over “data structure interview questions.” They show up in every technical interview.
– Use “coding interview preparation apps” that have questions about whiteboards or system design.
– Most of the best apps have built-in analytics that let you keep track of your progress.
– Set up regular practice interviews to work on both your technical and behavioral skills.
The End
With the right tools, practicing for coding interviews is not boring or too much anymore. The best apps for preparing for a coding interview let you solve real problems, take mock interviews, and look at data. These seven apps can help you every step of the way, whether you want to pass FAANG interviews or feel more sure of yourself in “online coding tests.”
