Daily System Design Interview Prep

What It Does

Every weekday morning at 7:30 AM IST, this workflow generates a system design interview question covering a different category each day — distributed systems, databases, API design, caching, messaging queues, social networks, streaming platforms, payment systems, and more. You get the full question, 5 key areas to cover, the most common candidate mistake, the scaling challenge that matters most, and a real-world company that built this exact system.

Why It Matters

System design interviews are the hardest round to prepare for because there's no equivalent of a daily coding challenge — no platform sends you one structured question per day with coaching included. Most engineers only study system design the week before an interview, which is too late to build the mental models that interviewers test for. Ten minutes every morning on one question, delivered to your Telegram, compounds into the depth that gets you promoted or hired at Staff level.

How It Works

What You Get

Each morning message includes:

1. A realistic system design question asked at top tech companies
2. Category and difficulty level (Mid-level, Senior, or Staff/Principal)
3. 5 key areas an interviewer expects you to cover
4. The most common mistake candidates make on this specific design
5. The scaling challenge that separates strong answers from average ones
6. A real-world example — which company built this in production and how

Who It's For

• Software engineers preparing for Staff or Principal engineer interviews
• Mid-level engineers targeting senior roles at FAANG or tier-1 companies
• Engineering managers who want to strengthen their technical depth
• Anyone who failed a system design round and wants structured daily practice

Setup

1. Create a Telegram bot — Open Telegram, message @BotFather, and follow the prompts to create a new bot. Copy the bot token.
2. Get your chat ID — Message @userinfobot on Telegram to retrieve your numeric chat ID.
3. Connect the Telegram node — Paste your bot token into the Telegram connector and set your chat ID in the workflow.
4. Submit the workflow — Once connected, submit and your first system design question arrives the next weekday at 7:30 AM IST.

Customize It

• Pair with a daily coding challenge for a complete morning interview prep stack in one Telegram chat.
• Change the chat ID to a group to practice system design with engineering colleagues.
• Adjust the schedule — Change the cron to 0 4 * * 1-5 (9:30 AM IST) if you prefer to read during your morning break.
