The Prep Crisis
The Problem Every Candidate Faces
Technical preparation is broken. Candidates switch tools constantly just to know what to solve next, losing focus and resetting their momentum.
Multiple DSA sheets scattered across browser tabs
No structured revision workflow to revisit weak spots
No clear, real-time visibility into overall progress
No personalized study plan tailored to current capabilities
Difficulty preparing for multiple target companies at once
Losing notes, bookmarks, and codes across multiple platforms
How It Works
What InLeet Delivers
A comprehensive coding preparation ecosystem designed to help you organize, solve, revise, and scale your tech preparation.
One Workspace
Track every question in a unified dashboard. Keep your solutions, notes, and revision flags in one single cloud-saved environment.
Smart Revision
Never forget difficult problems. Flag questions for dedicated revision rounds and study them based on structured spaced repeats.
Custom Sheets
Create company-specific roadmaps. Add any question from the pool, organize by topic, and prepare exactly for your next big interview.
Progress Analytics
Know exactly what remains. Visual tracker charts display completion percentage, topic-wise status, and revision volume in real time.
AI Sheet Generator
SoonGenerate personalized study plans. Specify your target company, prep duration, and skill gaps to get a custom learning route.
System Design Roadmap
Master LLD & HLD. Follow detailed modules on object-oriented architecture, SOLID principles, and large-scale distributed architectures.
Integrated Notes
Keep explanations right beside the questions. Jot down key patterns, dry-runs, complexities, and reminders directly next to the code.
Future Online Judge
PlannedPractice without leaving InLeet. An integrated sandbox editor lets you write, compile, and run code directly within the workspace.
Target Audience
Who is InLeet For?
Whether you are landing your first coding role or preparing for a senior engineering loop, InLeet structures your roadmap.
Students
Prepping for university placements or their first software engineering internships. Needs a structured roadmap from scratch.
Working Professionals
Preparing for interviews while holding down a 9-to-5. Needs structured spaced revision to stay fresh with zero wasted time.
Career Switchers
Moving from non-technical, testing, or operations roles into software development. Needs clear direction on what matters.
SDE 1 (Junior Devs)
Aiming for mid-level software engineering positions by reinforcing algorithmic foundations and data structures.
SDE 2 (Mid-Level Devs)
Levelling up to senior SDE roles. Needs core DSA practice plus Low Level and High Level System Design roadmap templates.
Experienced Engineers
Refreshing system design patterns, distributed caching, databases, and key DSA topics for tech lead loops.
The Comparison
Why Choose InLeet?
See how InLeet compares to traditional spreadsheets and scattered bookmarks.
| Capability | Other Methods | InLeet |
|---|---|---|
| Sheet Organization | Multiple spreadsheets across browser tabs | One unified, cloud-saved workspace |
| Revision Strategy | Bookmark questions and forget about them | Smart spaced repetition revision queue |
| Documentation | Separate notes files or local text files | Personal notes integrated beside questions |
| Progress Tracking | No overall stats, manual cell coloring | Unified visual analytics and progress meters |
| Personalization | Static pre-made templates only | AI-generated tailored sheets |
Evolution
The Journey of InLeet
From a single developer's spreadsheet frustrations to a unified preparation environment.
Problem Noticed
Phase 1Juggling multiple spreadsheets, Notion lists, and browser bookmarks. Progress was scattered and motivation was hard to maintain.
First Spreadsheet
Phase 2Built a master tracking sheet. It went stale as soon as multiple preparation paths (Blind 75, Striver SDE) were combined.
Blind 75 Web Tracker
Phase 3Developed a simple web prototype to track a single set of key questions with localized state storage.
Custom Sheet Builder
Phase 4Rewrote the platform to allow users to curate their own sheets and organize questions by topic and difficulty.
Revision Queue & Flags
Phase 5Integrated dedicated status markers (Solved, In Progress, Revise) and an automated queue for space-based revision rounds.
Public Launch
Phase 6Successfully launched the core InLeet platform for developers preparing for DSA coding interviews.
AI Sheet Generator (Soon)
Phase 7Leveraging generative AI to build customized preparation plans matching specific company filters and user timelines.
LLD & HLD (Soon)
Phase 8Extending study paths to Low Level Design (class diagrams) and High Level Design (system designs).
Community Workspace
Phase 9Collaborative prep workspaces, shared custom sheets, and community-driven coding groups.
Our Vision
We believe interview preparation shouldn't require dozens of spreadsheets, bookmarks, browser tabs, and notes. InLeet aims to become the single workspace where developers prepare for coding interviews—from DSA to System Design and beyond.
