Choose the role and, where available, the exact employer template you're preparing for.
Behavior, not judgment
Walk in already familiar with the interview.
Mirror lets you practice against the same pre-approved templates employers already run on HiringMirror — same competencies, same format, same rubric. Your real interview becomes your second take, not your first.

Here's what I noticed
"You began 6 of 7 answers with I think… — a pattern, not a personality trait."

From cold read to second take
Practice the interview
you're about to take.
Three steps between you and walking in already familiar with the format.

Observable feedback on tone, pacing, filler words, and structure, plus one focused thing to practice next.
Not a guess at what they'll ask
Practice on the exact
template employers use.
Every template on Mirror is the same one a hiring team configured on HiringMirror — same must-haves, same scoring guidance, same interview length. You're not rehearsing in the dark.

Same question, retaken
See yourself improve,
one take at a time.
Practice isn't just a score — it's a side-by-side you can actually see.
First take
"I think... um, we'd probably just... cache it? Maybe. If that makes sense."
Fillers: 23
Hedges: 9
Length: 1m 40s
Structure: Loose
Second take
"We'd cache the response at the edge and invalidate it on write — that keeps reads fast without serving stale data."
Fillers: 11
Hedges: 3
Length: 1m 12s
Structure: Situation → action → result

Cold Read
You're walking in on a first take. A short rehearsal could change that fast.
Your answers never leave this device — the score is just for you (and whoever you send it to).
What you actually get back
A report you can
practice against.
Every note is an observable behavior with a timestamp behind it — no labels, no diagnoses, no guesses about who you are.

What changes
after one rehearsal.
"I practiced on the exact template the company used a week later. Walking into the real thing felt like round two, not round one."
RS
Applied AI Engineer candidateHired after two practice sessions
"The before/after replay was the first time anyone showed me my filler words instead of just telling me to 'be more confident.'"
MK
ML Engineer candidatePracticed 3 sessions
"Knowing it was the same rubric the employer used took so much of the guessing out of prep. I knew exactly what to work on."

Before you start
Questions candidates
usually ask.
Will employers see my practice sessions?
No. Practice sessions are private by default. Nothing is shared with an employer unless you explicitly choose to send your Mirror card.
Is practicing free?
Yes. Starting a practice interview costs nothing. You can retake questions as many times as you'd like.
What if my target company isn't listed?
Pick the closest role track. You'll still get a template built around the same core competencies most teams screen for in that role.
How is this different from a generic mock interview?
Generic tools ask generic questions. Mirror's templates are the same ones employers configure on HiringMirror — same prompts, same rubric, same format.
Do I need to be applying somewhere to use it?
No. You can practice anytime to build the habit before you're actively interviewing.
