HLD - Overview

Introduction:

High level design is a phase in the SDLC where the overall architecture and structure of the system/application are planned and documented in a comprehensive manner.

This phase is crucial because it bridges the gap between the requirement specs and the actual implementation of these specs.
The goal of an HLD is to provide a blueprint or roadmap for how the system will function and how the various components involved will interact with each other.

Basic things to keep in mind:

• Requirement analysis (Functional and Non Functional)

• System architecture

• Module / Component Design

• Data design / interfaces / API Schema

• Tech Stack Selection

Things to note:

• You will be faced with an open ended problem in the interview

• Don't make assumptions. Ask the right questions and clarify.

• Drive the interview with interviewer's intent

• This round is not just about creating boxes

• HLD round isn't about coding, just focus on planning and architecture
