Gaurav Sen: System Design
One of the first channels to make system design interviews approachable, with whiteboard walkthroughs of scaling problems, sharding, consistent hashing and message queues. A good free starting point before committing money.

What it is
Whiteboard style system design videos covering both the interview classics and the underlying concepts, delivered as a worked thought process rather than a polished presentation.
Why the format helps
You watch someone reason, including the moments where a first idea gets discarded. That is much closer to what a real design interview looks like than a finished diagram, and it teaches the recovery moves that matter when your first approach does not survive a follow up question.
Where it fits
Excellent as an entry point and as a supplement. It is a video library rather than a curriculum, so bring your own structure or use it alongside a sequenced course.
Best for: engineers new to system design who want to try the material before paying for it.
