Summary

Two rounds for a new-grad infra/backend SWE role at what sounds like a big semiconductor company. Resume walkthrough and API stuff in round one, then live coding on HackerRank plus an API design discussion in round two. Felt okay about both but now sitting at 10 days past the promised 5-7 business day window with nothing from the recruiter.

Questions Asked (3)

Q1

Walk us through your resume and relevant experience.

Adaptability & Ambiguity
Author's notes

Pretty standard opener but I always underestimate how much they actually dig in.

Suggested Approach

Structure your resume walkthrough as a narrative that highlights your adaptability and ability to deliver results in ambiguous situations, tailored to Samsung's software engineering needs. Focus on 2-3 key experiences that demonstrate technical depth, cross-functional collaboration, and learning agility, connecting each to the role's requirements.

Pro tip: Quantify your impact and explicitly state how you navigated ambiguity or changing requirements; Samsung values engineers who can drive clarity and innovate under uncertainty.

1. Brief Introduction

Start with a concise summary of your current role and years of experience, setting the stage for your narrative.

2. Highlight Key Experiences

Select 2-3 roles or projects that showcase your technical skills and adaptability, especially those involving ambiguous or evolving requirements.

3. Emphasize Adaptability

For each experience, describe the situation, the ambiguity or challenge, and how you adapted to deliver results.

4. Connect to Samsung

Relate your experiences to Samsung's projects, technologies, or culture, showing how you can contribute to their software engineering team.

5. Conclude with Enthusiasm

Summarize your interest in the role and how your background aligns with Samsung's goals, inviting further discussion.

Key Points to Mention

  • Specific examples of adapting to changing project requirements or technologies
  • Quantifiable achievements (e.g., performance improvements, cost savings, user growth)
  • Experience with cross-functional teams and agile methodologies
  • Technical skills relevant to Samsung (e.g., embedded systems, mobile development, AI/ML)
  • Instances of taking ownership and driving projects from ambiguity to clarity
  • Continuous learning and staying updated with industry trends

Q2

API design questions covering how you'd structure and expose backend services.

Suggested Approach

Start by clarifying the requirements and constraints (e.g., consumers, scale, latency, security) before proposing any design. Then walk through a structured API design process: resource modeling, endpoint design, versioning, error handling, and security. Finally, discuss trade-offs and how you would validate the design with stakeholders.

Pro tip: Demonstrate awareness of Samsung's device ecosystem and backend constraints by mentioning how your API design would support multiple device types, handle intermittent connectivity, and ensure backward compatibility for long-lived products.

1. Clarify Requirements and Constraints

Ask questions to understand the use case, expected load, latency requirements, security needs, and existing systems. This shows you don't jump to solutions prematurely.

2. Model Resources and Relationships

Identify the core entities and their relationships. Use RESTful principles or GraphQL based on the use case, and define clear resource hierarchies.

3. Design Endpoints and Contracts

Define URIs, HTTP methods, request/response schemas, status codes, and error formats. Ensure consistency and idempotency where needed.

4. Address Cross-Cutting Concerns

Cover authentication, authorization, rate limiting, versioning, pagination, caching, and monitoring. Explain how these are implemented.

5. Discuss Trade-offs and Evolution

Compare alternatives (e.g., REST vs. gRPC), explain your choices, and outline how the API will evolve without breaking clients.

Key Points to Mention

  • RESTful principles vs. GraphQL vs. gRPC and when to use each
  • Versioning strategies (URI, header, media type) and backward compatibility
  • Error handling with standard HTTP status codes and consistent error payloads
  • Security: OAuth 2.0, JWT, API keys, and rate limiting
  • Pagination, filtering, and sorting for large datasets
  • Documentation and contract testing (OpenAPI/Swagger, consumer-driven contracts)

Q3

Live coding problem in a HackerRank environment (LeetCode-style algorithmic question).

Algorithms & Data Structures
Author's notes

Felt fine during it but you never really know.

AI HintsAI Generated

Suggested Approach

Start by clarifying the problem constraints and edge cases, then discuss a brute-force solution before optimizing with appropriate data structures. Implement the optimized solution cleanly, test with examples, and analyze time/space complexity.

Pro tip: Verbally walk through your thought process as you code, and proactively test edge cases like empty input or large values—interviewers value clear communication and thoroughness over silent perfection.

1. Understand and Clarify

Restate the problem in your own words and ask clarifying questions about input size, constraints, and expected output format. Confirm edge cases like empty input or duplicates.

2. Brainstorm Approaches

Discuss a brute-force solution first, then propose optimizations using appropriate data structures or algorithms. Compare trade-offs in time and space complexity.

3. Plan and Pseudocode

Outline the steps of your chosen approach in pseudocode or comments before writing actual code. This reduces errors and shows structured thinking.

4. Implement and Test

Write clean, modular code with meaningful variable names. Test with the provided examples and additional edge cases, debugging as needed.

5. Analyze and Optimize

State the time and space complexity of your solution. If time permits, discuss potential further optimizations or alternative approaches.

Key Points to Mention

  • Time and space complexity analysis (Big O notation)
  • Edge cases and input validation (e.g., empty input, large values, duplicates)
  • Choice of data structures (e.g., hash maps, heaps, trees) and why they are optimal
  • Trade-offs between different approaches (e.g., sorting vs. hashing)
  • Code readability and modularity (e.g., helper functions, clear variable names)
  • Testing strategy (e.g., unit tests, manual walkthrough with examples)
