From the plan to the decision

Everyone on the loop works from the same round, so their reads can sit side by side.

Plan every round before it starts

Start from a plan in the library or write your own, with suggested questions when a round needs one more.

Run the interview from the script

The clock runs, the script leads, and the interviewer marks each signal yes, no or not sure as they hear it.

Write it up while it is fresh

Readings carry into the write-up, and AI drafts the feedback from them. The recommendation stays the interviewer’s.

Decide with every read side by side

The debrief shows each interviewer’s recommendation, never averaged, and records the call with a reason if you give one.

In the AI era, the interview decides

Résumés and take-home tasks are easy to generate now. A live conversation, run the same way by every interviewer, is still hard to fake.

The same bar in every interview
Every round comes with its questions, timings and signals, so candidates are compared on the same evidence.
AI does the prep, people decide
AI suggests questions, screens applicants and drafts write-ups. Interviewers mark what they hear, and people make the call.
No bot, no recording
Nothing joins the call and no audio or video is stored, whether the interview is on a call or in the room.
No ATS to set up first
Positions, candidates and interviews live in one workspace, and write-ups copy into Greenhouse or Ashby later.

For everyone on the loop

  • Hiring managers

    Plan the loop once, see every interviewer’s read side by side, then advance, hold or reject in one place.

  • Interviewers

    Walk in with a script, timings and the signals to listen for. AI drafts the write-up from your notes and marks.

  • Recruiters

    Screen applicants against the role, book each interview on its round, and remind whoever still owes feedback.

  • Candidates

    Assessed on the same signals as every other candidate in the round, by interviewers who each file feedback before seeing anyone else’s.
