About codezilla

Interview Insurance for Senior Engineers

codezilla keeps you 75%+ interview-ready at all times — so a layoff never catches you unprepared. The learning loop covers all three pillars interviewers test: Technical, Behavioral, and System Design, for less than $1/day.

Our Story

Interview readiness that works around your career

The Problem

Most engineers are not keeping their interview skills sharp between job searches. When a layoff hits — or an opportunity opens — they are scrambling to re-learn patterns they last practiced years ago. By then, it is too late to prepare well.

The Insight

Genuine interview readiness requires more than grinding LeetCode. You need to understand the pattern, explain your thinking, write working code under pressure, and retain it days later. That is a learning science problem — and the learning loop is built to solve it.

How codezilla Works

codezilla uses the learning loop — Intro, Explain, Practice, Test, Review — to build genuine pattern mastery across 38 technical, system design, and behavioral topics. Each cycle takes 10-30 minutes. Your readiness score updates after every completed pattern, giving you a real-time view of where you stand across all three pillars interviewers test. See how the loop works.

Our Values

Principles that guide everything we build

🎯

Outcome-Driven

We measure results, not hours logged. Every pattern you complete moves your readiness score. The target is 85%+ across Technical, Behavioral, and System Design — not arbitrary completion certificates.

🕐

Flexible & Self-Paced

10 minutes on Tuesday, 3 hours on Saturday — it all counts. Insurance Mode is designed for engineers with real jobs and unpredictable schedules. No guilt if you skip a week; the platform waits for you.

💸

Affordable Access

Complete interview prep — Technical + Behavioral + System Design — for less than $1/day. That is 1/10th the cost of a single session with a human coach, available 24/7 on demand.

🔺

All Three Pillars Matter

Acing the algorithm round means nothing if you bomb behavioral. We track Technical (50%), Behavioral (25%), and System Design (25%) because that is what interviewers actually test for senior and staff roles.

Our Vision

Interview-ready engineers. A verified talent pool. A stronger hiring market.

We are building in phases — each phase unlocking the next level of impact for engineers and the companies hiring them.

Phase 1 — Now

Interview Insurance

Keep engineers at 75%+ interview readiness with the EEAVR loop — Expose, Explain, Apply, Verify, Review. All three pillars: Technical, Behavioral, and System Design. $29/mo, less than $1/day.

Phase 2 — Next

Stronger AI + Full Pillar Coverage

Behavioral STAR story bank with AI feedback. System Design test bank (conceptual, not whiteboard). Stronger Verify-stage scoring calibrated to senior/staff roles. Outcome tracking to visualise readiness progress over time.

Phase 3 — Future

Recruiter Marketplace

Engineers who reach 85%+ readiness opt in to a verified talent pool. Recruiters pay to search profiles filtered by readiness score, patterns mastered, and availability. Verified skills — not self-reported resumes. Only viable after 200+ active users.
