About InstantInterview.app and DailyCoding.dev

Daily Coding publishes one programming challenge every day. Everyone gets the same challenge, and it stays up for 24 hours, the idea is borrowed from Advent of Code, but it runs all year instead of twelve days in December. You write your solution in the browser and run it against the test cases...

Questions & Answers

As answered by people managing InstantInterview.app and DailyCoding.dev.

What's the story behind your product?

InstantInterview.app's answer

I was looking for a tool to practise my interview skills, but everything I found was either too expensive, didn't give useful feedback, or wasn't conversational so I built it for myself, then realised others needed it too.

DailyCoding.dev's answer:

I do Advent of Code every December and try to keep the habit going on LeetCode every January. It never lasted more than a week, too many problems, no reason to do this one today. So I built what I actually wanted: one challenge, the same for everybody, all year round. Seven months of evenings and about 470 commits later, it runs in 11 languages.

How would you describe the primary audience of your product?

InstantInterview.app's answer

Anyone anxious about upcoming interviews who wants realistic practice and proof they're improving.

DailyCoding.dev's answer:

Developers who want a small daily habit rather than interview grinding: people who enjoy Advent of Code and miss it in January, students and apprentices practising algorithms, and experienced developers warming up in a language they are currently learning.

Why should a person choose your product over its competitors?

InstantInterview.app's answer

Purpose-built voice to voice interviews with measurable feedback

DailyCoding.dev's answer:

Because it takes choice away instead of adding more. LeetCode and Codewars offer thousands of problems; Daily Coding offers the one that is live today. It is free with no paid tier, today's challenge works without an account, and the whole thing is open source under MIT, including the sandbox that runs the code.

What makes your product unique?

InstantInterview.app's answer

Real-time AI voice interviews with quantified feedback (STAR scores, WPM, filler rate), no scripts, measurable progress.

DailyCoding.dev's answer:

One challenge per day, and it is the same challenge for everyone. There is no catalogue to browse and nothing to pick, that decision is exactly what makes most people quit after a week. Once you submit, every other solution to the same challenge becomes readable, across all 11 languages.

Which are the primary technologies used for building your product?

DailyCoding.dev's answer:

Next.js 16 and TypeScript with the Monaco editor, deployed on Vercel. Submissions are executed on a self-hosted Piston instance on a Hetzner server, with typed test harnesses generated per language. Prisma for data access, Postgres DB
