Talk through behavioral questions out loud. Get scored feedback across 8 dimensions in seconds. Built for engineering leaders.
Used by engineers who got offers from
You know the questions. Answering them well is the hard part.
You can LeetCode your way through coding rounds. But most engineers wing behavioral interviews - and it costs them.
Your answer rambles for 8 minutes. You lose the interviewer's attention.
You know you led the project, but the way you tell your story doesn't reflect that.
You get the offer - but one level below where you should be.
You feel you do well but get one rejection after another.
This tool fixes all four.
How it works
Expert-level behavioral interview feedback in three steps.
Choose your scenario
Select your target role, pick from a list of real interview questions, or bring your own.
Have a real conversation
A voice-based AI interviewer follows up with probing questions, just like a real interviewer would.

Tell me about a time you had to make an unpopular decision...
Interviewer
Tell me about a time you had to make an unpopular decision with your team. What was the situation and how did you handle it?
Last year, I decided to pause all feature work for two sprints to pay down critical tech debt. The team was frustrated because we had just committed to a product roadmap with tight deadlines...
That sounds like a tough call. How did you communicate this decision to the team, and how did you get their buy-in?
I held a team meeting where I showed them our incident data - we'd had 3 production outages in 6 weeks, all caused by the same legacy service. I framed it as an investment: two sprints now would save us months of firefighting...
Tap to speak
Tell me about a time you had to make an unpopular decision with your team.
- Used concrete data (3 outages in 6 weeks) to justify the decision
- Demonstrated clear stakeholder communication by presenting a comparison framework
- Could quantify the impact more - what was the cost of each outage?
- Consider mentioning how you measured success after the tech debt sprint
Your answer demonstrates strong situational awareness by using incident data to frame the decision. To elevate further, quantify the business impact and tie the investment to measurable outcomes...
“We were averaging 3 P1 incidents per month. I gathered data, calculated 120h of engineering time lost, and presented a trade-off analysis to leadership...”
Your stories can land better than you think.
Most engineers undersell their experience - spending too long on context, skipping their most impressive actions, forgetting to quantify impact, and never mentioning what they learned. This tool catches all of it and shows you exactly how to fix it.
Every question you'll face in a real interview
Covers every signal area interviewers assess - calibrated for each role. Plus bring your own questions.
Tell me about a time you had to make an unpopular decision with your team.
Describe a situation where you had to rebuild trust with your team after something went wrong.
Tell me about a time you identified and developed a high-potential engineer.
How did you handle a situation where two senior engineers disagreed on a technical approach?
Tell me about a time you had to give difficult feedback to a high performer.
Company-specific interview prep
Every company evaluates behavioral interviews differently. Tailor your preparation to the company you are interviewing at.
Engineers who prepared
“After 5 sessions my CARL scores went from 4s to consistent 8s. I walked into my final round knowing exactly how to frame every story. Landed the EM role and negotiated £15K above their initial offer because I genuinely did so well thanks to the prep with this tool.”
David K.
Engineering Manager · Series B startup
Landed EM + negotiated £15K above initial offer
“My stories were pitching Senior, not Staff. After restructuring three key stories using the level assessment, I got the Staff offer I was actually interviewing for. Without this I would have not gotten a Staff level offer for sure.”
Priya S.
Staff Engineer · FAANG
Got Staff offer, avoided down-leveling
“The scoring showed me I was not articulating well my impact and showed me how to do it better. Three sessions later I was consistently scoring 7+ across all dimensions. Got a Senior EM offer with a £25K higher total comp than my previous role.”
Marcus T.
Senior Engineering Manager · Late-stage startup
Senior EM offer, £25K comp increase
What is CARL?
Context, Action, Result, Learnings - the framework top interviewers use to evaluate behavioral answers. Every practice session scores you on how well your story hits each element, so you know exactly what to sharpen.
Not another chatbot
Generic AI gives you encouragement. This gives you a score, a diagnosis, and a fix.

No way to track whether and if you improved between sessions.
Follow-ups
"Can you tell me more about that situation?" (same generic prompt every time)
Level signal
You get poor judgement of your level. Not calibrated against the rubrics that companies use.
