Here are 5 Tips for System Design interviews. They are helpful when preparing for a System Design interview.

1. Don't get into details prematurely

2. Avoid fitting requirements to a set architecture in mind

3. Keep it simple, stupid! Remember to look at the big picture and avoid too many hacks when solving.

4. Have justifications for the points you make. Don't use buzz words or half hearted thoughts in your design.

5. Be aware of the current solutions and tech practices. A lot of solutions can be purchased off the shelf which simplify implementation. You should be able to argue for a custom implementation with it's pros and cons.

Have these on the back of your mind during you interview, and all the best!
Here are three major points evaluated during the interview:
1. Clarity of Thought

a. Express your thoughts in a clear manner.

b. Justify your decisions. Critical reasoning and argument are key to a successful software design.

c. When faced with a problem, use standard approaches to mitigate it. For example, say you are faced with an availability problem. State that replication and partitioning help increase availability in general, and move on to offer a solution.

d. Don’t make points without thinking them through. Half-hearted attempts at solving problems are frowned upon heavily.

2. Know about existing solutions

a. Stay up to date with the current solutions in the market. This includes products and design practices. If NoSQL is being adopted left right and center, you need to be aware of it.

b. Know when to pick a solution vs. building something custom. If you name a product, you should be (generally) aware of the features it provides.

c. Design practices enable you to meet custom requirements. Examples are decoupling systems, load balancing, sticky sessions, etc…

3. Flexibility

a. Switch your targets as the requirements shift. If the interviewer wants to know about one particular part of the system, do it first.

b. Never have a set architecture in mind. We all try to fit requirements to a system, but only after it has been shaped by the initial ones. A rigid attitude creates a brittle architecture. It will break before you do.

c. Take a step back at times to make adjustments to the general architecture. Being focused on one part can narrow our vision and bloat those areas. There will be components which can be extracted out and extended to the rest of the system.

Design Underground System is a popular Leetcode design problem asked significantly at the company Bloomberg. For this problem, we must implement three functions check in, check out, and get average time. There are a couple approached to solve this design question, but the way I explain it is using two maps.

Using hashmaps to solve this problem is the best approach because it will allow you to have a constant time complexity for all functions in your class. For the check in functionality, we must allow a custom to check into a station a certain time. For check out, we must check out a customer at an end station at a specific time. Finally, getting the average time involves taking the average travel time of all previous travel between any two stations. Two maps is perfect for this design because we will always have unique id's for each customer, so we can compute averages in O(1) constant time complexity at any point.

The space complexity of our solution is going to be big oh O(N + M) where N is the number of customers that have checked in and M is the number of customers that have checked out. We must combine both N and M because a customer cannot be checked in and checkout at the same time.

I cover the systems design interview in more detail in my program Tech Interview Pro ( techinterviewpro.com/ ) if you are interested in learning more. We also do bi-weekly Live Q&As so have a look.

In this video, we discuss load balancing, CDNs, database replication, sharding, caching layers, database schema and indexes, distributed filesystems, and other ways to scale an application. You don't want to scale your design too early or needlessly, but consider where the bottlenecks are. Sometimes you will need database sharding for instance, while other times you may not need a database at all (ie., if the data does not need to persist to disk). Note: the concepts will differ somewhat for a frontend or mobile systems design, which are more focused on the client-side architecture and software design patterns.

At its essence, the Bloomberg Terminal is a near-real-time multi-window browser that must run efficiently and reliably on the desks of the most influential people in the global capital markets or trading floors operated by the world’s leading investment banks and hedge funds.

It combines a highly-scalable, proprietary data processing technology written in C++ with an embedded Chromium browser core and its V8 JavaScript engine. The result is a challenging, distributed run-time environment that must perform well and be measurable. The talk will cover some of the techniques used to develop and instrument this system.

System Design is an important part of computer science that lets you build and scale a consumer product. Can you imagine if Instagram takes 5 minutes to load? Or if it takes hours to do a Google Search, how many people would actually use it?

Probably very few. Here in this video we are going to talk about some of the methods and ways you can build a scalable and robust system that can handle a ton of users.

In this interactive session with JobTeaser, colleagues from our European headquarters in London share their perspectives on working at Bloomberg. They discuss how to create a meaningful career path and give some tips on how to ace your interview.
