Say hello interview and begin your System Design prep journey
Some interviews test what you know. The System Design Interview tests how you think. No tidy inputs, no green checks—just an open-ended problem and your ability to wrangle chaos into clarity. It’s the moment when whiteboards become battlegrounds and vague prompts like “design a messaging app” feel like code for “survive this mental obstacle course.” And yet, that’s exactly what makes it fun. So instead of dreading the unknown, let’s flip the script. Let’s treat this like the beginning of something great. Hello interview. Hello ambiguity, creativity, architecture, and trade-offs. Hello System Design! Let’s get to work.
