System design is one of the biggest hurdle in getting job at Amazon, Google, or Netflix, and most of the startups. I have seen many experienced developer with years of experience in their resume falling apart in this round because of lack of preparation and knowledge.
That’s why its extremely important to prepare well for interviews and its best to prepare the frequently asked System design problems like how to design YouTube, and how to design WhatsApp to start with.

7 Common System Design Problems for Practice
Here a couple of my favorite System design questions to learn essential System design concepts and principles
- Design YouTube or any other video Streaming service like Netflix, Hotstar, or SonyLiv (Solution)
We all have used YouTube and best thing about this question is that we all are familiar with most of functionality but when it comes to designing them its tricky but since we are only considering about technical aspect and not functional, this is a good question to start with. Think about different functions, scalability, performance and resiliency.
If cannot solve see this solution for detailed discussion.
2. Design WhatsApp or any other chat system (Solution)
Same like previous question, think about message distribution, recovery and scalability.
3. Designing a URL Shortening service like TinyURL (Solution)
4. Designing Instagram (solution)
5. Design a Library Management System (Solution)
6. Design a Parking Lot (Solution)
These are a few questions which I always practice before interview. Don’t think they are only 6, if you go in-depth it can take days to solve these questions and each one of them will teach you many essential system design concepts and challenges you face.
All the best with your interviews and don’t forget to share what is your favorite System design question.
