System design interviews aren’t hard because you don’t know enough. They’re hard because you have to balance clarity, depth, and time, all at once. It’s not a tech quiz. It’s a communication test wrapped inside a technical one. And here’s where most people slip: – They spend too long setting up the basics – Dive too deep into one component – Run out of time before reaching trade-offs The result? An incomplete answer that doesn’t reflect what you actually know. My friend Kamran (@aTechGuide) created a [ FREE ] 7-day email course to help you approach system design interviews like a structured conversation, not a rushed whiteboard dump. You’ll learn how to: ✅ Set the right direction in the first 5 minutes ✅ Keep your answer focused and flexible ✅ Finish strong, with trade-offs and real-world thinking The goal is to think clearly under constraints -> just like you do on the job.

@AlexHormozi - Find Smart people - Enable them - Hope they will stay

You don’t need to be smart to get rich, you just need to not stop.

3) Once bills are paid, More money is not Proportional to More Happiness

@AliAbdaal Went from "Put things on Calendar" to "Minimum things on Calendar" in his latest "Life Update" Learning as 🧵

2) Its ok to leave "Money on Table"

1) If money is no objective then will we continue to do what we do?

Shall we call @getdbt SQL on Steroids 🤔

"Fan Out" Pattern for building Home Timelines is officially deprecated in System Design Interviews @elonmusk has begin the era of next Generation Home timelines Thanks @Twitter Team CC: @alexxubyte

@elonmusk I think it paints a pretty decent picture Any suggestions what is Manhattan and what feature hydration is doing in Home Scorer? CC @alexxubyte

@elonmusk Tweeted Twitter Architecture 🐦 Let's try to make sense out of it 🧵

@elonmusk [READ Path] Left to Right - Iphone / Web Client connects with Federated Graph QL endpoint, which connects with Timeline Mixer to build the timeline - Android users are on legacy TLS - API path (which is being deprecated) and connects with Timeline Mixer to build the timeline

@elonmusk [Home Mixer] - It seems this is a new component being built in parallel to Timeline Mixer - It shall support Tweety pie, Social graph etc [Home Scorer] - This component is used to build the users home timeline

@elonmusk [Time Line Mixer Continued] - It supports tweet de duplication, hydrating tweets with conversation, pagination etc - Tweeets are then scored using Timeline scorer

@elonmusk [Time Line Mixer] - It is responsible for building user timeline by fetching tweets for the user from Timeline Service - It connects with People Discovery Service for user suggestions, Ad mixer for personalized ads

@elonmusk [Timeline Service] - Fetch tweets for the user based on his following [Timeline Scorer] - Applying scores on each tweet to sort them

@elonmusk [People Discovery Service] - This service is responsible for recommending users that we shall connect [Ad Mixer] - This service is responsible for fetching personalised ads based on users engagement on Twitter Platform

It will be interesting to have @elonmusk and @garyvee on a same panel. Discussing the role of EMPATHY and COMPASSION And it’s correlation with success.

What’s the cost of a VERIFIED FREE SPEECH ?

Brilliant advice

@elonmusk When shall we get the EDIT button?
