The loop
The loop: how a Beforehand mock interview works. Rehearse, see the truth, fix the moment, repeat.
Get the scorecard
Grounded in your real transcript - a readiness number you can trust, not vibes.
See where you lost the interviewer
The exact line where your answer turned generic, hedged, or showed no ownership.
Retry the moment
Re-record just that answer until it holds. Then walk into the real interview as yourself.
The scorecard
The scorecard points to the exact moment you lost the room.
Not a grade. Not a list of tips. The literal sentence where your answer weakened - in your behavioral or system design round - and a model of what a stronger answer sounds like.
Generic
You said what anyone would say.
No evidence
A claim with nothing behind it.
No ownership
A team story with no you in it.
Hedged
You undercut your own answer.
02:14
Signal lost - ownership
Interviewer asked: "Tell me about a hard technical call you made."
You said
"...so we decided to rebuild the pipeline, and it improved things a lot."
Why it weakened
A team decision with no you in it. Interviewers are listening for what you did, decided, and risked.
Stronger sounds like
"I made the call to rebuild it. Here's the trade-off I weighed, and what it cost us to get it wrong first."
Listening
The rehearsal room
It's just you and one realistic interviewer.
No audience. No grade you didn't ask for. A quiet, dark room where your first shaky run at a system design question stays between you and the work. Speak, get pressed on, try again.
Readiness is a trajectory
You were a 58. Now you're a 74.
One session sets your baseline. Each one after shows whether you're actually getting better - by dimension, over time, against the date that matters.
Readiness - 5 sessions+16 from baseline
Ready - 80

Common questions
How do I practice for a software engineering interview?
Beforehand runs you through a realistic SWE interview - behavioral, system design, coding, or debugging - out loud and in private. You answer, it follows up where you're weak, then gives you a transcript-grounded scorecard with the exact lines to fix.
Can I practice system design and behavioral interviews out loud?
Yes. Beforehand is voice-first: you speak your answers to system design, behavioral, coding, and debugging questions and get scored on what you actually said - clarity, structure, evidence, and ownership.
What SWE interview rounds does it cover?
Behavioral, system design, coding, and debugging rounds for internship, new-grad, and experienced software engineering roles. You set the role, company, and round before each session.
Is this a tool to help me cheat during a live interview?
No. Beforehand is for before. You rehearse in private, learn where you are weak, fix it, then walk in and do it yourself. There is nothing to use during a real interview, by design.
Who can review my mock interviews during beta?
Your sessions are not shared with employers. During private beta, the founder may review transcripts and scorecards to find trust blockers, improve prompts, and verify coaching quality before wider launch.
Better here than in the room.
Run one private readiness check, fix the weakest moment, then walk into the real interview knowing what your answer actually signals.
