Stripe Software Engineering Intern Interview Experience (2025–2026)

Overview

Stripe is a leading financial infrastructure platform that processes billions of dollars in payments annually. The company is known for its rigorous engineering hiring process and high standards for code quality. This article details the interview experience for a Software Engineering Intern position at Stripe's Bengaluru office during the 2025–2026 hiring cycle.

Interview Process

The interview process at Stripe for software engineering interns consists of four distinct stages:

1. Online Assessment – Conducted via HackerRank
2. Technical Screen – 60-minute coding interview
3. Virtual Onsite – Two rounds of practical exercises
4. Managerial Round – Behavioural discussion

Technical Rounds

Round 1: Online Assessment

The candidate received an online assessment invitation two days after applying. The HackerRank evaluation lasted 60 minutes and featured one implementation-heavy problem divided into three sequential sub-parts. Each subsequent part built upon the previous solution, making modular code essential for success.

Key Lesson: Writing modular, reusable code from the start is critical when problems are designed as progressive enhancements.

Round 2: Technical Screen

The technical screen lasted 60 minutes, comprising 45 minutes of coding and 15 minutes of discussion. The interviewer assessed the candidate on data structures and algorithms, focusing on arrays, maps, and string manipulation. The candidate solved two questions completely and discussed a third approach.

The interviewer emphasised these qualities:

• Clean, readable code
• Descriptive variable names
• Maintainable code structure
• Production-quality coding practices over pure algorithmic optimisation

Round 3: Virtual Onsite – Programming Exercise

The first onsite round centered on a data parsing and processing task. Rather than complex algorithms, the exercise evaluated the ability to handle and transform data effectively.

Round 4: Virtual Onsite – Integration Round

This round provided access to a private GitHub repository along with API documentation. Internet access was permitted. The tasks covered:

• File operations
• Data extraction
• External API integration
• Processing and handling API responses
• Debugging issues
