Amazon interviewers will ask you operational questions during an interview for a software developer's position to determine how you complete the tasks required by this role. They also want to learn that your techniques are similar to those of their current development team. It is best to respond to Operational questions succinctly and directly. You should always expect follow-up questions when an Amazon interviewer is asking about a specific task. This indicates that they have a special interest in the topic they are questioning you about.
