We built a crowdsourced interview question database for tech interviews

When prepping for tech interviews, my go-to strategy has always been to scout online for any interview questions and insights people have shared. However, this process is incredibly time-consuming. Information is scattered across multiple platforms: Leetcode Discuss, Glassdoor, 1point3acres (IYKYK) and often buried under low-quality or vague posts. Many threads are just people asking for questions rather than sharing them (Leetcode Discuss I'm looking at you), and even when questions are shared, they often lack enough detail to be truly useful. Typically you have to go through a lot of posts before landing on a good one. To solve this, we built interviewdb.io: a crowdsourced database where people can share real interview questions they've encountered. To incentivize contributions, we’ve implemented a points-based system: you earn points by submitting questions and use them to unlock others.

You might ask: Why Not Just Use Leetcode Tagged? We see InterviewDB as a complement to Leetcode Tagged, not a replacement. Here’s why: 1. Many companies are poorly covered on Leetcode Tagged, with little to no data. 2. No context on whether a question appeared in an OA, phone screen, or onsite. 3. Companies often tweak Leetcode questions, making them harder to recognize under pressure. Seeing real-world phrasing helps. 4. Leetcode doesn’t cover system design or company-specific interview formats/processes.

We launched recently and already have ~5,000 users contributing and benefiting. The more people join, the more valuable this will be for everyone. Would love to hear your thoughts and feedback!

Kinda sad that it has come to this.

Maybe I'm naive but I think an interview should be an honest exchange of what you actually know, not what you crammed for before the interview.

“Technical review by experienced developers Our team of engineers with experience at top tech companies reviews each question for technical accuracy, relevance, and clarity.”

Which engineers which top companies? It’s all very ambitious.

In fact, for me it is pretty hard if not impossible to remain genuine to my ability and personal touch to navigate corporate world having to swallow all those keywords and behave properly in front of interviewers. Thinking that hacking/mastering it is often the single way out.

It should be. If the interview tests for what you crammed for, it doesn't test for what you'll remember a month onto the job. That's a sub-optimal strategy for the interviewer.
