I spent a solid chunk of my prep time on Gaurav Sen's InterviewReady content before an interview loop, and I want to talk honestly about what it gave me and what it didn't-because I think a lot of people (including past me) treat "I watched all of Gaurav Sen's videos" as equivalent to "I'm ready," and those are not the same thing.
What InterviewReady actually is
Gaurav Sen is an ex-Google engineer and a genuinely excellent teacher. InterviewReady's content is built around deep, first-principles explanations of distributed systems concepts-consistent hashing, distributed consensus, operational transformation (the algorithm behind Google Docs' real-time collaborative editing), and coverage of systems most courses skip, like chess engines and live video streaming infrastructure.
There are also bi-weekly live Zoom sessions, which is a nice touch-direct instructor access is rare in this space.
What it gets right
The teaching quality is legitimately some of the best I've encountered. Gaurav doesn't hand you a memorized framework and call it a day-he actually explains why a distributed system behaves the way it does, at a level of depth that sticks with you. If your goal is building genuine intuition for how distributed systems work, not just passing an interview, this content delivers.
The gap I ran into
Here's the thing that became obvious about three weeks in: I could explain every concept Gaurav taught. I could not, at first, actually design something from scratch without freezing, because watching someone else reason through a problem and reasoning through one yourself are different skills that don't automatically transfer.
InterviewReady is fundamentally a video-first platform. There's no interactive sandbox where you build something yourself and get told what's wrong with it. You're watching a brilliant engineer think out loud, which is valuable-but it's passive. The muscle that actually gets tested in an interview is the one where you're the one thinking out loud, under a bit of pressure, with someone occasionally pushing back.
What actually closed the gap for me
I ended up supplementing InterviewReady with ScaleDojo, specifically because it's built around the opposite thing-instead of watching an explanation, you're on an interactive canvas actually assembling the architecture yourself, submitting it, and getting AI-scored feedback on the specific decisions you made. It's not a replacement for the depth InterviewReady gives you; it's the practice rep that depth alone doesn't provide.
A rough way I'd describe the difference: InterviewReady taught me why consistent hashing works the way it does. ScaleDojo was where I actually had to decide, cold, whether a given problem called for it-and got told specifically when I was wrong.
Who should use InterviewReady
If you learn well through deep, patient, first-principles explanation and you want real conceptual grounding before you start producing designs yourself, it's an excellent starting point. Just don't mistake finishing the video library for being interview-ready-the name is a little aspirational in that specific sense.
The honest takeaway
Depth and practice are two different inputs, and you probably need both. InterviewReady is one of the best sources I've found for the first one. It's worth pairing with something that forces you to actually build, not just understand, before you assume you're ready for the real thing.
