[Masterclass] How To Ace Your Big Tech Interview - System Design

System design is a crucial software engineer interview skill, especially for FAANG and Big Tech in general. It is effectively a requirement to be leveled at a senior software engineer or higher and will show up in mid-level engineer interviews as well (with the occasional appearance in even junior engineer interviews). The cool thing about system design (unlike data structures and algorithms) is that it's something you actually need to do on the job.

Here are our Top 5 points from the session (in no particular order):
- **Leverage engineering blogs of top companies** - And if you're applying to one of these companies, definitely read their blog. This will help you understand their high-level design and gives you a real-world example to anchor off of, as opposed to something more abstract and high-level that you would get from a traditional book.
- **Do NOT write code** - System design is a *high-level* exercise meant to gauge seniority. Writing raw code is the mark of a more junior software engineer, which is why you should never be writing code in a system design interview. Instead, draw boxes with arrows where the boxes represent components and the arrows represent how they interact.
- **There is no right answer** - One of the main reasons software is hard is because of how open it is. For any complex technical problem, there will be several good solutions, each with varying tradeoffs. System design is not like school or DSA where there is a singular right answer.
- **Understand the problem requirements** - System design problems are, by design, very open-ended. For example, if you get "Build the Twitter feed", there are so many features that make it up: There is no way you can design the entire thing in 1 interview round. Work with your interviewer to understand the scope of the problem and which parts should be prioritized.
- **Follow mature software principles** - The 5 covered in this presentation are robustness, scalability, performance, extensibility, and resiliency. Don't just get the happy flow working - Think about how your system will react when edge cases are hit and things go wrong.
