Adaptive AI mock interviews and hands-on labs on a real, disposable Postgres. Practice DevOps the way the job actually works, then walk into the interview ready.
Your first quiz is on us. No card to start.
A pod is stuck in CrashLoopBackOff. Walk me through how you'd debug it, step by step.
Reading about DevOps does not get you hired. Doing it does. Everything here is built to make you do the reps.
A real interviewer that asks, listens, and drills into your gaps. It scores every answer and adapts the difficulty as you go, so you practice the questions you are actually weak on.
Every lab spins up a live, disposable Postgres just for you. Run real queries, break things, get it back clean on the next attempt. No fake terminal pretending to be a shell.
Structured tracks for CKA, SRE, and cloud DevOps interviews. Each path knows what you have mastered and what to review next.
Most prep tools fake the terminal. We give you a live Postgres, isolated on its own branch, seeded and ready. Run the query, read the plan, break the index, and reset it on the next attempt. It costs us almost nothing when idle, so it is yours to experiment with.
