I built a tool to help devs benchmark their skills before interviews
Hey everyone! 👋
I'm launching Skillhacker — a simple platform where developers can test their knowledge, practice, and see how they stack up against the average.
🤔 Why I built this
Personal pain, honestly. I've been through dozens of technical interviews, and every time I got an invite, I'd feel this gnawing uncertainty: "Do I actually know my stuff? What are my blind spots? How do I compare to other mid-level/senior devs out there?"
There are tons of question banks and LeetCode-style platforms, but I couldn't find something simple that would:
Let me quickly test myself without committing to a 2-hour coding session
Show me where I stand compared to others (am I above average? below? where are my gaps?)
Give me a focused practice mode to drill weak spots before an interview
So I built it.
🛠 What's inside (MVP)
Quiz format: Multiple-choice questions (4 options) across different tech stacks
Two modes:
🎯 Testing mode — take a test, get your score, see how you compare to the community average
💪 Practice mode — drill questions, learn from mistakes, focus on weak areas
Benchmarking — see your level vs. the average participant
It's early stage, focused on the core loop: test → benchmark → practice → improve.
🚀 What's next
More tech stacks and difficulty levels
Detailed analytics (your weak topics, progress over time)
Community features (leaderboards, study groups)
💬 I'd love your feedback
Since I'm targeting the US/EU market, I'm especially curious:
Would you use this before interviews? What's missing?
What tech stacks should I prioritize? (Started with JS/TS, Python, SQL)
Is the benchmarking angle valuable, or do you prefer pure practice?
Be brutal — I need honest feedback to make this actually useful.
Thanks for reading! Happy to answer any questions in the comments.
