PlusWealth Capital Management LLP is a fast‑growing quantitative trading firm based in Gurugram. The company leverages advanced mathematics, data science, and cutting‑edge technology to design algorithmic trading strategies that operate across multiple asset classes. With a focus on high‑frequency and low‑latency execution, PlusWealth invests heavily in building a robust, scalable infrastructure that can handle massive market data streams in real time. The firm’s culture blends the rigor of finance with the creativity of software engineering, offering fresh graduates a chance to work on mission‑critical systems that directly impact trading performance. The role of C++ Developer / Infrastructure Developer is crafted for recent graduates who have a strong foundation in C++ and a passion for system‑level programming. As a member of the core engineering team, you will be responsible for designing, implementing, and optimizing components of the trading stack, ranging from market data ingestion pipelines to order execution engines. You will collaborate closely with quantitative analysts, senior developers, and operations engineers to translate complex financial models into high‑performance code that runs on Linux servers. Key Responsibilities: 1. Design, develop, and maintain high‑performance C++ applications that form the backbone of the trading platform. 2. Build and fine‑tune low‑latency networking modules for market data and order routing. 3. Implement efficient data structures and algorithms to process large volumes of tick‑by‑tick data. 4. Conduct profiling and performance analysis to identify and eliminate bottlenecks. 5. Write clean, modular, and testable code following industry best practices. 6. Develop automation scripts in Python/Bash for deployment, monitoring, and debugging. 7. Participate in code reviews and contribute to the continuous improvement of the codebase. 8. Collaborate with cross‑functional teams to integrate new trading strategies into the production environment. 9. Maintain comprehensive documentation for all infrastructure components. 10. Stay updated with emerging technologies and propose enhancements to the existing stack. Tech Stack: C++ (C++14/17), Linux/Unix, TCP/IP & UDP networking, Python, Bash/Shell scripting, Git, Docker, and performance profiling tools (e.g., perf, gprof). The role offers a clear growth path—from junior developer to senior engineer, and eventually to lead architect—based on technical mastery and contribution to the firm’s profitability. Joining PlusWealth provides exposure to real‑world financial systems, mentorship from seasoned traders and engineers, and the opportunity to see your code directly influence market outcomes. The fast‑paced environment encourages continuous learning, making it an ideal launchpad for ambitious technologists.

Explain OOP (Object-Oriented Programming) principles with real-world examples in C++. 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.
