About the role

Nudge is an emerging Indian fintech startup that aims to become the country’s ultimate commerce rewards platform. By allowing users to scan shopping bills, link accounts such as Gmail, Swiggy, and Zepto, and engage in gamified experiences, Nudge turns everyday purchases into rewarding experiences. The company’s mobile-first approach has resulted in a rapidly growing user base across both Android and iOS, positioning it as a high‑impact player in the rewards‑as‑a‑service space.

The mobile team at Nudge has adopted a modern, cross‑platform architecture built on Kotlin Multiplatform (KMP) and Compose Multiplatform. This enables a single codebase to power native experiences on Android and iOS while still allowing platform‑specific customisation where needed. As a Software Engineering Intern – Client (Mobile), you will join this fast‑moving team, work under a dedicated mentor, and contribute directly to features that reach thousands of daily users.

Key Responsibilities

  • Develop and ship user‑facing screens for bill scanning, account linking, rewards dashboards, and in‑app games.
  • Translate UI/UX designs into responsive, animated interfaces using Compose Multiplatform and SwiftUI where applicable.
  • Integrate RESTful APIs, manage networking, caching, and offline data handling.
  • Implement device‑level functionalities such as camera access, permission handling, push notifications, and deep linking.
  • Write unit and UI tests, profile performance, and debug crashes to ensure a stable release.
  • Participate in code reviews, follow the CI/CD pipeline, and assist in publishing builds to Play Store and App Store.
  • Leverage AI coding assistants (Claude Code, Cursor, GitHub Copilot) to accelerate development while maintaining code quality.
  • Explore shared Kotlin code execution on iOS, identify platform‑specific gaps, and propose solutions.
  • Document feature implementations and contribute to internal knowledge bases.
  • Collaborate closely with product, design, and backend teams to align on requirements and delivery timelines.

Tech Stack: Kotlin Multiplatform, Compose Multiplatform, Kotlin, Swift, Jetpack Compose, SwiftUI, REST/JSON APIs, Coroutines/async‑await, Git, AI coding tools.

Growth Path: High‑performing interns are often offered full‑time Mobile Engineer roles, with opportunities to lead feature teams, specialise in cross‑platform architecture, or move into product ownership.

Why Join Nudge: You will ship code to real users on both platforms, learn a niche yet powerful cross‑platform stack, receive direct mentorship from the app’s creators, and work in an AI‑first development environment that values speed and quality. This internship is a launchpad for a career in modern mobile engineering within a vibrant startup ecosystem.

Round 2: Technical Interview 1 Core Tech Stack (Kotlin, Java, Swift, Flutter, React Native, Jetpack Compose, Swiftui, REST APIs) & Live Code Tracing Explain your thought process aloud. Analyze time & space complexities before coding.
Round 3: System Design & Problem Solving Database Schemas, APIs & Architecture Basics Clarify edge cases, diagram schemas cleanly, and discuss scalability trade-offs.
Round 4: HR & Cultural Fit Discussion Nudge Core Values, Learning Agility & Offer Terms Demonstrate passion, strong communication, and readiness for full-time collaboration.
Technical questions 5
Explain OOP (Object-Oriented Programming) principles with real-world examples in Kotlin. Answer
Model answer: 1. Encapsulation (data hiding via private fields/getters). 2. Abstraction (hiding implementation complexity). 3. Inheritance (code reusability). 4. Polymorphism (method overriding/overloading).
What is the time and space complexity of QuickSort vs MergeSort? Answer
Model answer: QuickSort: Average O(N log N) time, O(log N) space. Worst O(N^2). MergeSort: Guaranteed O(N log N) time, but requires O(N) auxiliary space.
Explain the difference between SQL Indexing (B-Tree vs Hash) and when not to use an index. Answer
Model answer: Indexes speed up SELECT queries via B-Trees. However, they slow down INSERT, UPDATE, and DELETE operations because indexes must be updated on disk. Avoid on low-cardinality columns (e.g., boolean flags).
What happens under the hood when you enter a URL in a browser? Answer
Model answer: 1. DNS lookup (resolves IP). 2. TCP 3-way handshake (SYN, SYN-ACK, ACK). 3. TLS negotiation for HTTPS. 4. HTTP GET request sent. 5. Server responds with HTML/CSS/JS. 6. Browser renders DOM & CSSOM tree.
What is the difference between REST and GraphQL APIs? Answer
Model answer: REST uses multiple fixed endpoints with possible over/under-fetching. GraphQL uses a single endpoint allowing clients to query exact fields in a single request.
Behavioural & HR questions 3
Why do you want to join Nudge as a Software Engineering Intern - (Client / Mobile - Android, iOS)?
Highlight Nudge's market reputation, recent tech innovations, and how your skills in Kotlin directly solve their team's objectives.
Describe a challenging bug or academic project roadblock and how you resolved it.
Use the STAR method: Situation (project context), Task (what needed solving), Action (specific tools/logic applied), Result (quantifiable positive outcome).
How do you handle strict deadlines or sudden scope changes?
Explain your prioritization strategy, proactive communication with mentors/peers, and agile mindset.
