14-Day Prep Plan

TL;DR

• This plan is meant to create rhythm, not overwhelm.
• The structure alternates between runtime depth, React depth, architecture/system design, and behavioral preparation.
• Every day should include reading, active recall, and at least one spoken answer out loud.
• If a topic still feels slow after the 14 days, that becomes the focus for the next week.

Context

The original prep-plan resource was already solid. The main thing missing was a clean place inside the site where it connected to the deeper knowledge pages and the coding practice content.

The Approach

Week 1 — JavaScript depth and async fluency

Day 1

• review JavaScript Closures & Scope
• explain stale closures out loud
• practice one closure-based utility

Day 2

• review Async JavaScript: Promises, async/await, Generators
• implement Promise.all or Promise.allSettled
• answer one async ordering question out loud

Day 3

• review JavaScript Event Loop & Runtime Model
• draw the browser and Node loops from memory
• explain a button-click lifecycle out loud

Day 4

• review Browser APIs & Observers
• build one small observer-based example
• explain when you would use IntersectionObserver vs MutationObserver

Day 5

• coding practice on Practice: Arrays or Practice: Searching
• focus on clarity of explanation while coding

Day 6

• rotate through Interview Q&A Bank
• answer three JavaScript questions without notes

Day 7

• review weak spots from the week
• do one timed coding question and one short spoken mock answer

Week 2 — React, system design, and principal storytelling

Day 8

• review React Rendering Model
• explain keys, reconciliation, and render vs commit

Day 9

• review React Hooks & Effects
• walk through stale-closure fixes and “you might not need an effect”

Day 10

• review React Performance Patterns
• use the React Profiler or simulate a profiler discussion

Day 11

• review Frontend System Design
• sketch one system-design answer with trade-offs

Day 12

• review API Patterns and Microservices Patterns
• explain protocol choice, idempotency, and outbox patterns out loud

Day 13

• write or rehearse 3–6 STAR stories from real projects you can discuss safely
• focus on scope, conflict, decision-making, and measurable outcome

Day 14

• run a mini mock loop:
  • one coding problem
  • one system design prompt
  • one behavioral story

Trade-offs

• A 14-day plan creates momentum, but it cannot replace repeated mock interviews.
• Broad review can build confidence, but targeted repetition is still the fastest way to fix weak spots.
• Time-boxing helps consistency, but some principal-level topics need deeper follow-up beyond the two-week pass.
