SDM Interview Preperation

What does a software development manager do at amazon?

Software Development Managers own the design, development, testing, deployment, and maintenance of the company’s software applications, systems, and technology projects. As a manager, you own building, managing, focusing, developing and engineering teams that meet the needs of the business and work well with other stakeholders and engineers. You draw from a deep and broad technical expertise to mentor engineers and provide leadership on complex technology issues in the company. While you may possess deep technical skills, you spend the majority of your time building great software by directing and managing the engineers who work for you. To sum up a Software Development Manager is a hybrid of system designer, people manager, roadmap/customer satisfaction driver, and a project manager.

  • How do you determine the effectiveness of your solutions?
  • How do you assess system quality?

Technical Tips

Often times, software systems need software components, something to store data, something to make decisions (i.e. business logic) and API’s, component relationships, and data flows. Reviewing software system design diagrams (i.e. SOA or distributed software systems) can be helpful for preparation.

Scaling is a critical component of software design at Amazon. Be familiar with common techniques to create scalable and highly available systems. This would include the use of data redundancy, fault tolerance, and horizontal scaling.

Write a list of requirements on the board, and keep asking questions. This should be the first thing you write out.
Be prepared to white board. Practice diagramming a design on a white board or even using pen and paper.
Interact with your interviewer and dig for clarification. Your interviewer will not try to trick you. Questions may be intentionally vague to push your innovation.
Keep the customer front of mind. Who is the customer, and what problem are you solving for them?
Begin drawing a diagram once you've done enough digging to begin white boarding your system design solution. Start with shapes to represent different software components and data sources, and then arrows connecting them to show web services, APIs, and interactions between components.
