interview preparation - system design


System design interviews can be a challenging and nerve-wracking experience, especially for engineers who have little experience with the process. One way to prepare for a system design interview is by using a standardized template that can guide your thinking and help you organize your thoughts. In this article, we'll be discussing a template that can be used to structure your responses in a system design interview, and how to use it effectively to impress your interviewer.


Brief about the problem

This section should provide a brief overview of the problem that the system is being designed to solve. This could include information on the industry or domain that the system will be used in, as well as the specific business or technical problem that the system is meant to address.

Functional requirements

Functional requirements are the specific features and functionality that the system needs to have in order to meet the needs of its users. For example, a social media platform might have functional requirements such as user login, signup, profile creation, and the ability to post and view content.

Non-functional requirements

Non-functional requirements are the qualities or characteristics that a system must possess in order to be considered successful. These could include things like availability, reliability, performance, consistency, read vs write heavy, security, and monitoring.


This section should include information on the resources that the system will need in order to operate effectively. This could include things like resource estimations, the main domain size, how many operations the system will need to handle, and the amount of storage required.

High level

This section should provide a high-level overview of the system's architecture and data flow. This could include a diagram or illustration that shows the different components of the system and how they interact with one another. This could include components and Data flow.


This section could include any additional information or observations that the interviewer would like to make about the system design. This could include any trade-offs that were made during the design process, any potential issues that were identified, and any areas where further research or development is needed.


System design interviews can be intimidating, but with the right preparation and mindset, you can impress your interviewer and land the job. By using a standardized template like the one outlined in this article, you can structure your responses and communicate your design effectively. Remember to practice, be confident, and keep learning to improve your skills.
