The ultimate practice tool

Your interview partner for anything that gets graded, judged, or performed. It asks out loud, listens while you reason it through, and refuses to move on until the gap is closed.

The problem

Reading is not the same as being asked.

Whatever you're preparing for, whether an interview, a viva, a pitch, a board exam, or a presentation, the room asks questions you can't predict. Most people over-prepare on the material and under-prepare on the one thing that decides it: being interrogated, in real time, on what you only half-know.

MockLabs solves the

retrieval-under-pressure

gap that you keep tripping up on.

Out loud, under pressure

It asks out loud. You answer out loud.

You can read your notes alone and you can write your answers alone. The one thing you cannot rehearse alone is being asked. So MockLabs speaks its questions, hears you reason through the answer, and follows up on what you actually said rather than what it planned to ask next.

Push-to-talk, so it listens only while you hold the key. No ambient listening, no transcription bleed.

Voice mode (push-to-talk)

Hold space (or the mic button) to speak. Your partner speaks back. Best for closing the gap to a real interview, and for spotting filler words.

Would rather type? Text mode runs the same interview, with code, math and a full transcript afterwards. Switch whenever you like, mid-session.

Two modes

From topic drills
to a full mock interview.

Pick the right pressure for where you are: focused training when you're shoring up gaps, mock interview when you're a week out.

01 / TRAIN

Socratic training

Pick a topic. Your interview partner asks questions, watches your reasoning, and refuses to move on until the gap is closed. Hints available at a small mastery cost.

How a session feels

It's not a quiz. It's an interview partner that listens.

  1. 1
    A question lands, sized to your current masteryDifficulty rises and falls with your last few answers, so you stay in the productive struggle band.
  2. 2
    You answer in your own wordsType or talk. Your partner parses the actual reasoning, so partial credit is real partial credit.
  3. 3
    Your partner probes gaps before letting you advanceWrong answers don't get corrected, they get questioned. The point is to find the misconception, not paper over it.
  4. 4
    Mastery updates. Weak subtopics surface tomorrow.A persistent map of what you actually know, and a daily plan for what to fix next.
Q3bayesian inferenceMedium
Two coins are flipped. Given that at least one is heads, what's the probability that both are heads?
1/2, since there are two outcomes for the other coin, so half are heads.
Reconsider the conditioning. List the four equally-likely outcomes for two flips, then strike the one ruled out by “at least one heads.” How many remain, and how many are (H, H)?
Right, (T,T) is gone, leaving three. Only one is (H,H). So 1/3.
Exactly. Now: how does the answer change if instead you’re told the first flip was heads?
