engineering interview prep

Land the six-figure engineering job.

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?

“Pressure scales with absolute temperature at fixed volume (Gay-Lussac). Cold morning → lower T → lower P; driving heats the tire → higher T → higher P…”

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.

More than a bigger pile of problems.

Most tools hand you practice questions. Overclocker is the interview itself — rehearsed, ranked, and coached.

A real interviewer — not a question bank

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.

A ranked, competitive arena

Timed, Elo-ranked sprints against the clock. Build the speed and composure real interviews test — the way no flashcard deck ever could.

Feedback that coaches you

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.

Not flashcards. Real derivations, taught the way an interviewer expects you to reason.

Beam Bending & Deflection

Why a beam can be perfectly safe and still feel like a trampoline

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.

Questions, answered

What's included in the free plan?

The easy Mechanical fundamentals (lessons plus a set of sample problems) and progress tracking. No credit card required, and it never expires.

What do I get with Pro?

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).

Which disciplines are covered?

We're launching deep on Mechanical Engineering. The other nine disciplines are rolling out with the same lessons, instant grading, and mock interviews.

How do the AI mock interviews work?

A realistic interviewer questions you on your chosen discipline, adapts to your answers, and gives feedback at the end. It's a Pro feature.

Can I cancel anytime?

Yes. One click in Settings, and you keep access through the end of your billing period.

Who is Overclocker for?

Students prepping for internships and new-grad roles, and working engineers brushing up before interviews.

How do I get help?

Built by engineers, for engineers

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.
