A plan for every round of your hiring loop
Each interviewer gets the questions, timings and signals to listen for. No bot joins the call, and the call is never recorded.

The interview loop
No single interview decides the hire. Each round scores one to three competencies, and every must-have is read at least twice, by a different interviewer each time.

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.
Start from a free plan
Each plan is a time-boxed script for one round, with what every question is for and the signals to score against.

Questions
- What is Hirezen?
- Hirezen is interview software for hiring teams. Each round of a position’s interview loop has a plan: the questions to ask and the signals to listen for. Interviewers mark those signals yes, no or not sure as they hear them, AI drafts the write-up from their notes and marks, and each round’s debrief puts every interviewer’s marks and recommendation side by side. No bot joins the call, and no audio or video is recorded.
- Does Hirezen record or transcribe interviews?
- No. No bot joins the call, and no audio, video or transcript is stored, whether the interview is on a call or in the room. The interviewer types notes and marks signals as they go, and the write-up is drafted from those.
- What’s the difference between a plan, a round and a loop?
- A loop is every round a candidate goes through for one position, in order. A round is one stage of it — a screen, a coding interview, a system design interview — with its own length and interviewers. A plan is what happens inside one round: an opening, the questions and a close, with the signals to listen for under each question. The plans in the library are free to read without signing up.Browse interview plans
- How do I make sure each round tests something different?
- Name the competencies the hire is decided on — the skills this role turns on — and mark which are must-haves. Each round then says which competencies it scores, up to three, and each question can be tied to the one it was written for. A grid of competencies against rounds shows where the loop is thin: a must-have that fewer than two rounds both claim and ask about, and a round claiming a competency it has no question for. Both are flagged, not blocked.
- Is there an interview scorecard?
- Yes — in Hirezen it’s the write-up, and most of it is filled in during the interview rather than from memory afterwards. Under each question are signals, short statements of what to listen for, and the interviewer marks each one yes, no or not sure as they hear it. They then give one recommendation, from Strong No to Strong Yes. Interviewers on the same interview can’t see each other’s write-ups until they have filed their own, and the debrief shows every recommendation side by side, never averaged.
- What does AI do in Hirezen?
- It suggests questions for a round, screens applicants against the role, and drafts each write-up from the interviewer’s notes and marks. It never marks a signal or gives the recommendation: the interviewer does. An assistant in the app also makes changes a person asks for, and asks that person to approve before it records a decision, a rejection or an offer.
- Do I need an ATS to use Hirezen?
- No. Positions, candidates and interviews live in one Hirezen workspace, so there is nothing to connect first. If your team keeps its hiring record in an ATS, a write-up — one interviewer’s or all of them at once — copies out formatted for a Greenhouse scorecard, or as plain text for Ashby or anywhere else.
- Is Hirezen free?
- Yes. The free plan covers one open role at a time, up to 10 teammates, and 20 AI candidate screenings a month, with no feature held back. Paid plans run more open roles at once.See pricing
