Questions that have appeared at Morgan Stanley for an engineering (Case Study) interview.

1. System Design

Question: How would you go about designing a high-frequency trading platform? What factors would you take into account to ensure the system is efficient, secure, and can handle high volumes of transactions?

Question: Imagine you're tasked with designing the back-end for a large-scale, real-time data processing system. What would your design look like? What technologies would you use and why?

Question: Explain how you would design a system to handle a massive influx of data, say from millions of IoT devices. How would you ensure it's both scalable and reliable?

2. Problem Solving

Question: A system you designed has been experiencing intermittent failures. The logs aren't showing anything unusual. How would you go about diagnosing and fixing the problem?

Question: Suppose you're in charge of a system that's running slowly. Your team has tried optimizing the code, but it hasn't helped. What other strategies might you try?

Question: You've been tasked to reduce the load time of a website without altering its existing functionalities. What steps would you take to achieve this?

3. Project Management

Question: Imagine you're in charge of a project that's running behind schedule. How would you get it back on track, considering both the technical and human aspects of the project?

Question: Suppose you've finished a project, but the client isn't happy with the result. How would you handle this situation?

Question: How would you manage a situation where you have to deliver a project under tight deadlines and resources are limited?

4. Process Optimization

Question: How would you approach optimizing a legacy system that is critical for the company but is causing performance bottlenecks?

Question: Suppose the software testing process is taking too long and is causing delays in deployment. How would you optimize the testing process?

Question: If you found that a specific process is consuming a large amount of resources (like CPU or memory), what steps would you take to optimize it?
