Interview Prep

Pass a real PLC interview. Not just the filter.

6 graded tracks from Junior to Senior. Every track mixes Q&A rounds with timed live-coding scenarios, and awards a verifiable certificate when you pass.

How tracks work

Structured like an actual hiring loop.

Each track is a sequence of rounds: a Q&A round, a live-coding scenario, a follow-up Q&A, another scenario. Grading is objective and on the clock. Either you passed, or you didn’t.

Q&A rounds

Multiple-choice and trace questions calibrated to the role. Junior fundamentals, senior PID and safety.

Live-coding rounds

Write a ladder program against a live scenario under a time limit. Automated tests grade it.

Graded on the clock

Every round has a duration. You either finish in time or you don't — same as the real thing.

Certificate on pass

Four of the tracks award a dated, signed certificate with a verification URL. Attach it to a job application.

The tracks

Pick your level. Then pick a specialty.

Track outlines are public. Specific questions, scenario slugs, and grading rubrics open after sign-in so the rounds stay honest.

Inside a track

A round-by-round loop that mimics the real thing.

The Mid track, for example, opens with a fundamentals Q&A, hands you a motor start/stop to code, then timers, then a state-machine scenario. Forty minutes, end to end.

  • Q&A rounds. Reuse the topic quizzes — same question types, same pass threshold.
  • Live-coding rounds. A scenario briefing opens. You write ladder logic in the editor. Tests run.
  • Advance or fail. Pass the round — advance. Fail — end-of-track feedback tells you where you tripped.
  • Certificate. Tracks flagged “awards certificate” produce a downloadable PDF on pass.

Walk into the interview knowing you’ve done this already.

Start with the Junior track — it’s free, and it’s a fair read on whether you’re ready.
