Build a search box that hits /api/search as the user types. What edge cases come to mind?

Debounce input, cancel stale requests, handle empty state.

Good. Why 300ms specifically, and what would change at 100ms?

How it Works

Three steps to interview-ready

Choose your target

Select the company, role, and seniority level you're preparing for. We'll customize everything to match.

Practice with AI

Start mock interviews — coding, system design, or behavioral. Our AI adapts difficulty to push your limits.

Get your report

A PDF coaching report with rubric scores, the exact moments quoted back from your session, and a prioritized improvement plan — free on every run.

What sets us apart

The four things every other platform misses

Built specifically for frontend interviews — not a generic DSA bank with a frontend tag.

AI Interviewer with Follow-ups

Not a static grader. The AI acts as a real interviewer — asking follow-up questions, probing trade-offs, giving hints when you're stuck, and adapting difficulty to your level.

Rubric-Based Coaching Reports

Every session generates a detailed report: competency scores, evidence from your session, code quality analysis, communication feedback, and a prioritized improvement plan.

System Design Whiteboard

Design frontend architectures on an Excalidraw whiteboard. Draw component trees, data flows, and state management strategies under real constraints — just like a senior-round onsite.

Company-Targeted Prep for 60+ Companies

Question style, difficulty, and evaluation criteria are calibrated per company. Google SD rounds differ from Flipkart MC — we prep you for the interview you'll actually face.

Two Ways to Prep

Practice rounds or simulate the full interview

Choose focused single-round drills to sharpen specific skills, or run a complete multi-round mock interview tailored to your target company and role.

Timed Practice Rounds

Single-round drills

Pick a round type, company style, and duration. Solve one focused problem with AI evaluation and a coaching report at the end. Perfect for daily reps and targeting weak areas.

FAQ

Frequently asked questions

Product

What types of interviews can I practice?

Frontend School supports coding rounds (React, JavaScript, TypeScript, machine coding in a live IDE), system design rounds (frontend architecture with an Excalidraw whiteboard), behavioral rounds (STAR format with AI follow-ups), and hiring manager rounds. Within coding, you can practice DSA, machine coding, theory, and HM rounds.

How is this different from LeetCode or Pramp?

LeetCode is a problem bank — it doesn't simulate an actual interview. Pramp connects you with other candidates, which is inconsistent. Frontend School gives you an AI that acts as a real interviewer: it asks follow-ups, adapts to your answers, gives hints when you're stuck, and generates a rubric-based coaching report after every session. Everything is frontend-specific — not generic DSA.

How does the AI interviewer work?

The AI interviewer adapts to your skill level in real time. It asks contextual follow-up questions, challenges your trade-off decisions, and evaluates your responses against the same competency rubrics used by real interviewers at top companies.

Is this useful for experienced engineers too?

Absolutely. We support SDE-1 through Staff/Principal. The AI adjusts difficulty and expectations to your target level. Senior engineers find the system design and HM rounds especially useful.

What companies are covered?

60+ companies including Google, Meta, Amazon, Apple, Microsoft, Netflix, Uber, Stripe, Airbnb, Flipkart, Swiggy, CRED, Razorpay, Meesho, Adobe, and Spotify. Each company track is calibrated to their known interview style.

How detailed are the coaching reports?

Reports include rubric-based scoring across multiple competencies, specific evidence quoted from your session, code quality analysis, communication feedback, and a prioritized improvement plan. Think of it as a debrief from a senior engineer who just watched your entire interview. They're included free on every session.

Pricing

What's included for free?

You get 1 practice session and 1 mock interview simulation to try the platform. No credit card required — just sign up and start. Buy credit bundles when you're ready for more. Coaching reports are free on every session.

How does pricing work?

Pay-as-you-go credit bundles. Buy session credits or simulation credits — use them anytime, they never expire. No subscriptions, no recurring charges. PDF coaching reports are included free on every session.

Refunds

What if I'm not satisfied?

Unused credits are refundable within 7 days of purchase, as long as none of the credits from that purchase have been used. Approved refunds are processed within 5–7 business days. Consumed credits are non-refundable. Full terms: /refund-policy.
