Voice debrief
Listening…
Just wrapped the Stripe onsite — system design round. They had me design a rate limiter and I fumbled the Redis part. Confidence? Maybe a two out of five.
You talk for sixty seconds after the interview.
Everything you need
Lytmus is built for the part of the search nobody tracks — the interviews themselves. Watch it work.

Sixty seconds of voice after each interview becomes structured rounds, questions, and confidence scores.

↗ Most loops end at the onsite — system design
Funnel, response rates, and confidence by topic — computed from your real interviews, not vibes.

The AI coach reads your weakest topics and drills exactly those — not a generic question bank.
How it works
Every round you log becomes data. Data becomes patterns. Patterns become targeted coaching — on exactly the topics costing you offers.
Drop companies in as you apply. Set stage, role, level, and location. The stats strip updates in real time.
After every interview, add the round, capture the questions asked, your approach, and your confidence score.
The coach reads your data — which rounds you lose, which question types score low — and drills exactly those weak spots.

FAQ
Lytmus is an interview tracking tool for software engineers. It lets you organize your job applications on a kanban board, log every interview round, capture every question asked with your approach and confidence rating, and view analytics that show where you lose offers. It also offers an AI coach that uses your own data to identify gaps and ask targeted follow-up questions.
Yes. The Lytmus free tier includes unlimited job applications, interview rounds, question capture, and full metrics. The product is completely free through July 2026 — no credit card required.
Unlike a spreadsheet, Lytmus captures the full depth of each interview — the rounds, questions asked, your approach and confidence — and computes analytics automatically. It shows your offer rate, response rate, and confidence gaps by topic without any manual calculation. The AI coach then uses that data to identify patterns you can't see yourself.
The AI coach reads your actual confidence ratings by topic across all your past interviews. Instead of generic advice, it targets the specific areas where your confidence is lowest — if you've rated distributed systems questions 2/5 across multiple interviews, the coach drills you on that specifically. Available on the Pro plan ($15/month).
Yes. Your questions, approaches, solutions, and notes are private to your account. Lytmus never shares your data with third parties and never uses it to train AI models. On the Pro plan, you can optionally grant read access to your career coach.
Lytmus supports all common software engineering interview formats: Recruiter Screen, Hiring Manager Screen, Technical Phone, DSA/Coding, System Design (HLD/LLD), Behavioral/Leadership, Take-home, Pair Programming, Bar Raiser, and more.
The only interview tracker that turns your own data into a personalized AI coach — targeting exactly where you lose offers.
