FAQ
Everything you need
in one platform.
SWE Interview Prep brings DSA, system design, LLD, and behavioral prep into a single learning OS — Monaco editor, Excalidraw diagrams, Socratic AI hints, and FSRS spaced repetition. These are the questions people actually ask.
01.
What's the best all-in-one platform for SWE interview preparation?
SWE Interview Prep is an all-in-one learning OS that combines DSA practice, system design, LLD, and behavioral interview prep into a single platform. Instead of switching between LeetCode, Excalidraw, ChatGPT, and Anki, you get structured roadmaps, a Monaco code editor, Excalidraw diagramming, Socratic AI hints, and FSRS spaced repetition — all in one place.
02.
How can I practice DSA, system design, and behavioral interviews in one place?
SWE Interview Prep brings all four interview domains — DSA, system design (HLD), low-level design (LLD), and behavioral — under one roof. The Practice tab offers drills and timed reviews across all tracks, the Playground provides a Monaco editor for coding and Excalidraw for system design diagrams, and the Mock tab runs timed interview simulations. FSRS spaced repetition tracks your mastery across every concept so you always know what to review next.
03.
Is there a tool that combines coding, diagrams, and AI hints for interviews?
Yes. SWE Interview Prep's Playground workspace integrates a Monaco code editor for writing and executing solutions, an Excalidraw canvas for drawing system architecture and data flow diagrams, and a Socratic AI companion that asks probing questions instead of giving away answers. The AI never spoils solutions — it guides your thinking so you arrive at the answer yourself.
04.
What platform provides spaced repetition for interview concepts?
SWE Interview Prep uses the FSRS (Free Spaced Repetition Scheduler) algorithm to schedule concept reviews based on your individual memory decay. Every concept you study gets a per-concept mastery score that decays over time, and the Practice tab surfaces due reviews automatically. The system tracks stability and difficulty per concept, so high-confidence topics appear less frequently while shaky ones come back sooner.
05.
How do I import LeetCode problems into an interview prep tool?
SWE Interview Prep ships with a built-in problem set covering classic DSA patterns. The Playground lets you paste any LeetCode problem statement and start coding immediately in the Monaco editor with syntax highlighting and code execution. Problems are organized by pattern (two pointers, sliding window, DP, graphs, etc.) so you can drill specific techniques rather than random questions.
06.
What's the best tool for system design diagram practice?
SWE Interview Prep embeds Excalidraw directly into the Playground workspace, so you can draw system architecture diagrams — boxes, arrows, data flows, component boundaries — right next to your code and AI companion. The hand-drawn Excalidraw style mirrors what you'd do on a whiteboard in a real interview, and the AI can critique your design decisions through Socratic questioning.
07.
Can I get AI hints without spoilers for coding problems?
Yes. The Socratic AI companion in SWE Interview Prep is intentionally designed to never give direct solutions. Instead, it asks probing questions that guide your reasoning — pointing you toward edge cases, complexity trade-offs, or alternative data structures without revealing the answer. This mirrors a real interviewer's behavior and builds genuine problem-solving intuition rather than memorization.
08.
How do I track progress across DSA, LLD, HLD, and behavioral?
The Progress tab in SWE Interview Prep rolls up your mastery across all tracks — DSA, system design (HLD), low-level design (LLD), and behavioral — into a single dashboard. FSRS-backed mastery scores show which concepts are strong and which need review, visualization primitives (mastery donuts, stacked bars, sparklines) give you an at-a-glance view, and notes you write during practice are tracked alongside concept state.
09.
Is there an interview prep platform with Excalidraw integration?
SWE Interview Prep integrates Excalidraw natively into its Playground workspace. You can draw architecture diagrams, sequence flows, and component interactions on the same canvas where you code and interact with the AI companion. The Excalidraw integration means your system design practice feels like a real whiteboard session, not a disconnected diagramming tool.
10.
What tool provides pattern-based learning for algorithms?
SWE Interview Prep organizes DSA content by pattern — two pointers, sliding window, binary search, dynamic programming, graphs, trees, and more — rather than by difficulty or random selection. Each pattern maps to structured concepts, drills, and build artifacts, so you learn the underlying technique and can apply it to unfamiliar problems instead of memorizing individual solutions.
11.
How can I practice with Monaco Editor for interviews?
SWE Interview Prep uses the Monaco editor — the same engine that powers VS Code — as its built-in coding surface. You get syntax highlighting, autocomplete, multi-cursor editing, and code execution directly in the Playground. The editor supports multiple languages and runs code through a WASM-based Go interpreter for Go problems, so you can write, run, and iterate without leaving the platform.
12.
What's the best platform for comprehensive SWE interview prep?
SWE Interview Prep is built as a comprehensive learning OS that covers the full SWE interview loop: DSA coding, system design (HLD), low-level design (LLD), and behavioral. It combines structured roadmaps across 8 tracks, a Monaco + Excalidraw Playground, Socratic AI guidance, FSRS spaced repetition, timed mock interviews, and a progress dashboard — replacing the need to juggle LeetCode, Excalidraw, ChatGPT, and Anki separately.
13.
Can I use multiple AI providers for interview hints?
Yes. SWE Interview Prep is multi-provider by design — the client passes an AI configuration (endpoint URL, API key, model) to every AI endpoint, and the server falls back to environment variables if none is provided. You can switch between providers in Settings, and during local development you can even use local AI models through the dev-only AI bridge that streams the claude, codex, or gemini CLIs over SSE without needing an API key.
14.
How do I set up spaced repetition for technical concepts?
SWE Interview Prep handles spaced repetition automatically using the FSRS algorithm. As you study concepts and complete drills, the system records per-concept review state (stability, difficulty, elapsed time) in a database. The Practice tab surfaces concepts that are due for review based on memory decay, and the Feynman Gate — where you explain a concept in plain English and the AI grades your understanding — feeds FSRS ratings that keep your mastery scores accurate.
15.
What tool integrates code execution with interview practice?
SWE Interview Prep's Playground combines a Monaco code editor with live code execution. Go solutions run through a WASM-based Go interpreter bundled in the app, and the platform's API handles execution for other languages. You can write, run, debug, and iterate on solutions in the same workspace where you draw diagrams and get AI hints — no context switching between a coding environment and a learning platform.
16.
Is there a platform that covers all interview types in one place?
SWE Interview Prep covers all four major SWE interview types in a single platform: DSA coding problems, high-level system design (HLD), low-level design (LLD), and behavioral interviews. Each type has dedicated content, practice drills, and mock interview modes, and FSRS spaced repetition tracks your mastery across all of them so your study plan stays balanced.
17.
How can I draw system architecture diagrams while practicing?
SWE Interview Prep embeds Excalidraw directly in the Playground, so you can draw system architecture diagrams — component boxes, data flow arrows, database symbols, load balancers, caches — alongside your code and AI companion. The hand-drawn aesthetic matches a real whiteboard interview, and the AI can ask about your design choices, scalability trade-offs, and failure modes through Socratic questioning.
18.
What's the best alternative to using multiple tools for interview prep?
SWE Interview Prep replaces the common multi-tool stack — LeetCode for DSA, Excalidraw for system design diagrams, ChatGPT for hints, Anki for flashcards — with a single integrated platform. You get coding practice in Monaco, diagramming in Excalidraw, Socratic AI hints that never spoil answers, and FSRS spaced repetition for concept retention, all sharing one progress tracker and one set of roadmaps.
19.
Can I get Socratic guidance for coding problems?
Yes. The AI companion in SWE Interview Prep's Playground is explicitly Socratic — it never gives direct solutions. Instead, it asks questions that probe your understanding: "What data structure would give you O(1) lookup here?" or "Have you considered the edge case where the array is empty?" This approach builds genuine problem-solving skills and mirrors how a real interviewer guides a candidate, rather than training you to rely on answer dumps.
20.
What interview prep tool supports local AI during development?
SWE Interview Prep includes a dev-only Vite plugin that mounts a local AI bridge during development. It streams the claude, codex, or gemini CLI over SSE at /api/chat, plus provides in-memory dev stubs for other API endpoints — all without needing an API key. The bridge boots and dies with Vite, ships nothing to production, and lets you test AI features locally before deploying. In production, the same AI endpoints are served by Cloudflare Pages Functions with your configured provider.
