I’ve spent months preparing for system design interviews.
I’ve read the books, watched countless videos, and practiced designing systems on my own. But every time an actual interview came up, there was still that familiar anxiety.
Not because I didn’t know the concepts — but because I didn’t know how I’d perform under pressure.
Would I freeze when asked a follow-up?
Would I be able to justify my decisions?
Would I know what to say when the interviewer challenged my design?
Reading and watching videos can’t answer those questions.
The goal isn’t just to teach system design. It’s to recreate the pressure of a real interview so that when the actual day comes, it feels familiar instead of intimidating.
If DevGrill can make your real interview feel like just another practice session, then it’s done its job.
