The complete interview simulator for hardware engineers — learn the concepts, drill them in a ranked arena, and rehearse the real thing with a live AI interviewer until you walk in ready.
Why does your tire pressure drop on a cold morning but rise after a long drive?
AI score88/100
What you did well
Tied pressure to absolute temperature and named Gay-Lussac's law.
What you can improve on
Note the volume isn't perfectly constant — the tire flexes slightly under load.
Train for interviews at
Most tools hand you practice questions. Overclocker is the interview itself — rehearsed, ranked, and coached.
Talk through problems with a live AI interviewer that asks follow-ups and tells you how you came across: your pace, filler words, and confidence. Not a recording you submit and forget.
Timed, Elo-ranked sprints against the clock. Build the speed and composure real interviews test — the way no flashcard deck ever could.
Every answer comes back with what you did well and what to fix — plus a skill profile. Like a hiring manager, not a red X.
A real free tier — not a trial — then plans priced below the alternatives. Cancel anytime.
Built deep first. The rest of the disciplines are coming — same lessons, same instant grading.
Not flashcards. Real derivations, taught the way an interviewer expects you to reason.
Beam Bending & Deflection
Two beams can be equally far from breaking, yet one barely moves while the other bounces like a diving board. Strength and stiffness are different questions, and that gap is where engineering interviews are won.
Integrate the elastic-curve equation twice, apply the boundary conditions, and you have derived the cantilever tip deflection every interviewer asks for:
You will not memorize that formula. You will derive it, then prove it in the live sandbox and a graded problem.
The easy Mechanical fundamentals (lessons plus a set of sample problems) and progress tracking. No credit card required, and it never expires.
Every lesson and all 162 interview-grade problems with full worked solutions, unlimited AI mock interviews, and the ranked Arena. $20/month, or $190/year (about $15.83/month).
We're launching deep on Mechanical Engineering. The other nine disciplines are rolling out with the same lessons, instant grading, and mock interviews.
A realistic interviewer questions you on your chosen discipline, adapts to your answers, and gives feedback at the end. It's a Pro feature.
Yes. One click in Settings, and you keep access through the end of your billing period.
Students prepping for internships and new-grad roles, and working engineers brushing up before interviews.

Technical interviews test the fundamentals you forget six months out of a textbook, and cramming formulas the night before doesn't work. Overclocker turns the concepts interviewers actually probe into deep, interactive lessons and realistic practice.
