Preparing for the Software Engineer interview at Minted requires a balanced approach. You must demonstrate strong technical fundamentals while showcasing your ability to collaborate effectively in a fast-paced environment.

The hiring team evaluates candidates across several core dimensions:

Technical Rigor & Algorithmic Problem-Solving – You must be comfortable writing clean, efficient, and bug-free code under time constraints. Interviewers look at your ability to explain your thought process out loud, analyze time and space complexity, and optimize your initial solutions.

System Architecture & eCommerce Domain Knowledge – For senior and principal roles, you must demonstrate a deep understanding of distributed systems, API design, caching strategies, and database modeling. Showing familiarity with eCommerce challenges—such as inventory management and transactional consistency—is highly valued.

Proactive Communication & Collaboration – Engineering at Minted is highly cross-functional. You need to show that you can translate complex technical concepts for non-technical stakeholders, ask clarifying questions, and actively listen to feedback during collaborative coding sessions.

Culture Alignment & Resilience – The team values builders who take ownership of their work and remain resilient through ambiguity. Be prepared to share concrete examples of how you have navigated changing priorities, resolved technical conflicts, and supported your teammates.

The interview process at Minted is designed to evaluate both your practical coding skills and your high-level system design capabilities. While the exact steps can vary slightly depending on the seniority of the role, candidates can generally expect a multi-stage process spanning several weeks.

The journey begins with an initial recruiter screen to discuss your background, career goals, and alignment with the role. This is followed by a technical screening stage, which typically involves a live coding session or an online assessment. Minted often partners with Karat to conduct these initial technical screens, allowing for a standardized evaluation of your coding and problem-solving speed.

If you pass the technical screen, you will move on to a conversation with the hiring manager to discuss your past projects, leadership style, and technical depth. The final stage is a comprehensive onsite (or virtual onsite) loop consisting of four to five rounds. These rounds cover whiteboard coding, system design, practical day-to-day work scenarios, and cultural fit conversations with senior leadership or VPs.

The timeline above outlines the typical progression from your initial contact to the final decision. Candidates should use this structure to pace their preparation, focusing heavily on algorithmic speed during the early stages and shifting toward system architecture and behavioral scenarios as they approach the onsite loop.

To succeed in the Minted interview loop, you must understand the specific expectations for each technical and behavioral evaluation area.

Algorithmic Problem-Solving (Karat & Live Coding)

This area evaluates your ability to translate logical thoughts into working code. You will face standard data structure and algorithm challenges where the focus is on correctness, efficiency, and code cleanliness.

Be ready to go over:

• Array and String Manipulation – Solving search, sort, and sliding window problems efficiently.
• Recursion and Memoization – Knowing when to use recursive patterns and how to optimize them using caching.
• Time and Space Complexity – Providing accurate Big-O analysis for your solutions and proactively suggesting optimizations.
• Advanced concepts (less common) – Multi-pointer techniques, graph traversal (DFS/BFS), and dynamic programming.

Example questions or scenarios:

• "Given a list of items with associated prices, find the combination of items that closest matches a target budget without exceeding it."
• "Write an algorithm to find the longest common substring among a set of product descriptions."

System Design & Architecture

For Senior Software Engineer and Principal Engineer candidates, this is a critical round. Interviewers want to see how you design reliable, scalable, and maintainable systems that support business growth.

Be ready to go over:

• Microservices & API Design – Structuring clean, decoupled services with well-defined REST or GraphQL APIs.
• Database Scaling & Consistency – Choosing between SQL and NoSQL databases and managing data replication and caching.
• Load Balancing & CDN Integration – Designing infrastructure to handle massive traffic spikes during seasonal promotions.
• Advanced concepts (less common) – Event-driven architectures, message queues (e.g., Kafka, RabbitMQ), and database sharding.

Example questions or scenarios:

• "Design a notification system that alerts customers when an item in their cart goes on sale or is low in stock."
• "Architect a digital asset management system that handles high-resolution image uploads, resizing, and fast delivery to global users."

Behavioral & Culture Fit

This round assesses your interpersonal skills, leadership qualities, and how well you align with the collaborative, design-driven culture at Minted.

Be ready to go over:

• Conflict Resolution – Navigating disagreements constructively with engineering peers or product managers.
• Ownership & Accountability – Taking responsibility for production outages or missed deadlines, and implementing corrective actions.
• Mentorship & Growth – Actively helping team members improve their technical skills and fostering an inclusive environment.
• Advanced concepts (less common) – Leading cross-functional alignment initiatives and managing technical debt in legacy systems.

Example questions or scenarios:

• "Tell me about a time when you had to deliver a critical project on a tight deadline with incomplete specifications."
• "Describe a situation where you had to advocate for technical debt reduction to product stakeholders who wanted to focus solely on new features."
