Quit the hunt for up to date interview questions
2,484 hand picked questions
Technical interviews are a numbers game that many candidates lose. We’ve hand picked 2,484 theory and coding questions so that you don’t have to waste time searching random websites for the most up to date interview questions.
62+ topics
Regardless if you’re preparing for a senior backend engineering role or a junior frontend role, we’ve got the questions to make sure you’re well prepared for whatever the interview throws at you.
PDF export
We all know that last minute prep on train to the interview can be the difference between landing the job and not. PDF export allows you to take our solutions with you wherever you go. So that you can always be revising even if you have no internet.
Algorithm visualizer
Most CS degrees and Bootcamps don't teach data structures and algorithms the way they are asked in interviews. That's why we've integrated an algorithm visualizser which deepens your understanding by showing you what's happening under the hood.
Solutions in 5 languages
Not everyone uses the same programming languages. We’ve made sure all our coding solutions are available in the most popular interview languages: Python, JavaScript, Java, C++, and Go.
Time & Space Complexity Analysis
Understanding how fast an algorithm runs and how much memory it uses is a crucial part of any coding interview. All our coding questions include time and space complexity explanations.
What our customers say
Dan
Software Developer
"I thought my CS degree would have prepared me well for technical interviews, but there was always one or two questions that I didn't know. When I started using TechPrep I found it much easier to pass my technical interviews."
Brian
Software Engineer
"I used to waste lots of time searching for up to date interview questions, but when I found TechPrep it was so nice to be able to spend all that time I used to spend searching for questions into just studying the answers."
