Show HN: LeetEngineer – The LeetCode for Non-IT Engineers (HR → technical)

https://leetengineerai.com
1•Daneng•3h ago
Hi HN — I’m Daniel, the founder. I built LeetEngineer because as an engineer I found generic interview prep doesn’t cover real engineering interviews.

LeetEngineer helps candidates prepare end-to-end:

Paste a job post and get HR screening questions + technical interview questions automatically.

Generate scenario-based technical questions tailored to the role.

Receive suggested answers and tips for presenting your knowledge effectively.

Why it’s different

Focused on engineers — not generic whiteboard practice.

Tailored to real job descriptions, so prep aligns with the company’s expectations.

Helps candidates who don’t know exactly what to expect in interviews.

What I’m looking for from HN

Honest feedback: does this solve a real pain for engineering interviews?

Feature suggestions — what would make you actually pay for this?

Early testers willing to try it for free in exchange for feedback.

Quick note: this isn’t a polished company launch — it’s a product I built to solve my own interview prep problems. I’d love critiques and ideas.

— Daniel (founder) — https://leetengineerai.com
