What this playlist covers

Code With Aryan LLD Interview Preparation Playlist by Code With Aryan runs to 36 videos across 5 sections: LLD Fundamentals & Principles, Creational Design Patterns, Behavioral & Structural Design Patterns, Real-World LLD Implementation Projects and Concurrency & Multithreading. Tick each video off as you finish it — progress is saved in this browser, and syncs across devices once you sign in. Nothing here is gated and there is no signup to start.

LLD taught from SOLID outward, with the most project implementations here — and a single video on concurrency.

Who it is for

Someone preparing for machine coding who wants principles before patterns. Like the other LLD playlist here, it is the wrong category if your round is high-level design.

How to work through it

  1. 01LLD Fundamentals & Principles (3) — SOLID. Short, and everything after depends on it.
  2. 02Creational Design Patterns (6) then Behavioral & Structural (12).
  3. 03Real-World LLD Implementation Projects (14) — the largest section and the reason to pick this one. Attempt, then watch.
  4. 04Concurrency & Multithreading (1). One video; treat the topic as uncovered and read elsewhere.

What it does well

  • 14 project implementations, more than any other LLD playlist here — and machine coding rounds are projects, not quizzes.
  • Opens with SOLID rather than jumping to patterns, so the patterns arrive as consequences rather than trivia.
  • Creational and behavioural/structural patterns are split sensibly across 18 videos.

Where it falls short

  • Concurrency and multithreading gets 1 video out of 36. Thread safety is asked in machine coding rounds and you will not be ready from this.
  • 3 videos on fundamentals is brisk if SOLID is new to you.
  • No high-level design content at all.

What to pair it with

  • Coder Army LLD — 22 pattern videos against this one's 18, and a 6-video OOP foundation.
  • Code With Harry OOP — The 37-video OOP grounding if the 3-video fundamentals section moved too fast.
  • System design sheet — For the HLD half of the loop, which no LLD playlist covers.
