There are many principles used in application programming. The Amazon interviewer is asking you about one of these. You should be able to easily answer this question based on your education and experience. The key is to use non-technical, easy-to-understand language when describing a principle to the interviewer. You may not be familiar with the depth of their technical background or their ability to understand complex concepts. Communicating clearly and effectively helps you in the interview and demonstrates your ability to collaborate with individuals from across Amazon's organization regardless of their technical knowledge. Interviewers are always looking for this skill when interviewing solutions architects.

"Single responsibility is the theory of a class or process doing one specific thing. This is also known as high cohesion. While each class or process within an application normally starts with a single responsibility or high cohesion, they evolve as programmers attempt to add responsibilities to the class. This sometimes gets out of control to the point where the class becomes ineffective and needs to be rewritten from scratch."
