For recruiters

You keep your promise. Every time.

You're the one the candidate remembers.

Knowback closes the loop automatically after every interview — so your reputation stays intact, no matter what the hiring manager does.

The reality

You care.
The process doesn't.

01
Your calendar is back-to-back

Giving every candidate the feedback they deserve takes time you simply don't have. It's not that you don't want to — it's that the day never slows down.

02
Hiring manager wrote just "Reject"

You don't want to lie. You don't want to embarrass yourself. So you say nothing — and the candidate thinks you ghosted them.

03
Your reputation follows you forever

Companies change. The candidates you treated well — or didn't — remember you at every company you'll ever work at.

04
You lose good candidates to silence

They accepted something elsewhere while you were waiting for the hiring manager. One nudge earlier would have saved it.

How it works

One install.
Every interview covered.

Interview ends. A few questions arrive.

Advancing or not? Next steps and timeline. If rejecting — a few structured tags. The candidate gets clarity. You get closure.

We remind you before the silence gets awkward

No new tool to learn

We extend the tools you already use — your calendar, your email. Knowback doesn't ask you to change how you work. It fits around it.

Control the pace of your pipeline

See which processes are moving and which are stalling. Adjust timelines, close loops early, and keep candidates warm — all from one place.

You have one reputation.
We help you protect it.

Knowback gives you a private score — response rate, average reply time, ghost count. Visible only to you. No public leaderboard. No judgement.

Just the honest mirror you've never had. And you'll also see how candidates perceived each interview — straight from their own words.
