What is Machine Coding?
What is Machine Coding? Learn what a Machine Coding Round is, how it differs from DSA & LLD, and why Flipkart, Uber, Swiggy and more use it onsite.
Machine Coding is a practical software engineering interview round where candidates are asked to design and implement a working software system within a limited time.
Unlike a traditional DSA interview, which mainly focuses on algorithms and data structures, a Machine Coding Round evaluates how well you can design, structure, and write real-world software.
Companies such as Flipkart, Myntra, Swiggy, Cred, Razorpay etc use Machine Coding Interviews to evaluate a candidate's practical software engineering skills.
A typical Machine Coding Round may ask you to build a system such as a Parking Lot, Elevator, Movie Booking System, Vending Machine, Splitwise, or In-Memory Database.
During the interview, interviewers generally look at:
- Object-Oriented Programming (OOP)
- SOLID principles
- Design patterns used
- Clean and maintainable code
- Extensibility and flexibility
- Handling changing requirements
The objective is not simply to make the application work. Your solution should be well-designed, easy to understand, maintainable, and extensible when new requirements are introduced.
In simple terms
Machine Coding is an interview where you turn a real-world problem statement into a working, well-designed piece of software.
It tests not just whether you can code, but how you design and write code.
