How it works
Grading that reads your actual work
Submission
A 6 m simply supported beam carries a 12 kN point load 2 m from A. Find the reactions.
ΣFy = 0: Ay + By − 12 = 0
ΣMA = 0: 6·By − 12(4) = 0
By = 48/6 = 8 kN
Ay = 12 − 8 = 4 kN
Line 2 · moment arm
The 12 kN load sits 2 m from A, not 4 m. Your ΣFy and the form of ΣMA are both right — the arm is the only thing that broke.

- Step 1
Submit your work
Type it, photograph it, upload a PDF, or sketch it on canvas — whatever matches how you actually solved it.
- Step 2
We find any errors
Not a generic “wrong.” The exact step where your reasoning broke, against a weighted rubric.
- Step 3
Track real progress
Numeric problems need a correct answer. Conceptual ones need 80%+. Nothing counts as solved by accident.

Questions people actually ask
Is this basically LeetCode, but for engineers?
That's the idea. Instead of coding puzzles, you get the mechanical and electrical engineering questions that actually come up in interviews — and instead of a test runner checking your output, an AI grader reads your reasoning the way an interviewer would.
Are these real interview questions?
Yes. Every question has been verified through real interviews — not scraped off a forum and not invented by an AI.
How is my work graded?
An AI grader reads what you actually wrote — your reasoning, your setup, your work — against a rubric built for that question, not just a final-answer checker. That works the same way for open-ended conceptual questions and for numeric ones: you can get a numeric answer right and still lose points for an unsound method, or vice versa.
How can I submit my work?
However you'd actually do it: type your answer, photograph handwritten work, upload a PDF or image, or draw it directly in the browser.
Which disciplines are covered?
Mechanical and Electrical are fully live today, with hundreds of questions each across every major subfield. Civil and Chemical are next.
Is it free?
Yes — no paywall, no plan to upgrade to. Grading is capped at a daily quota shared by everyone, just to keep the AI cost sustainable; browsing and unlocking questions is unlimited.
How do I find the right questions for my interview?
Paste the job description and we'll rank the question bank by how directly each one exercises what that job demands — or if you don't have a posting in hand, answer four quick questions about your discipline, focus areas, and level.
