Software development is a complex process that requires excellent research skills. A candidate should be able to describe several sources like StackExchange and Github that they use to discover how to overcome problems they encounter while coding. Software developers also succeed more often when they are willing to ask colleagues and subject matter experts about thorny technical issues that have them stumped. What to look for in an answer:

• Awareness of online resources
• Research skills
• Ability to ask questions when needed

In the past couple of decades, software technologies have begun to evolve at a pace that makes it necessary for developers to move from one language or framework to the next every few years.

A candidate should be able to describe strategies for staying current. What to look for in an answer:

• Strategies for continuous learning
• Awareness of current technology trends
• Ability to quickly learn new technology tools

Software developers often need to communicate technical limitations or requirements in layman's terms when they negotiate or collaborate with users and product owners outside of an IT department.

Agile development has become a popular methodology for technology departments large and small. In many cases, Agile principles are only partially adopted in favor of more structured planning. A candidate will likely bring up these issues during an honest assessment of Agile methods. Agile works well for smaller projects that can be divided between one or more small teams. It doesn't work as well for large software projects that require long-term planning. What to look for in an answer:

• Knowledge of Agile method
• Ability to weigh the pros and cons of design methods
• Past experience with Agile projects
