How can you reduce the amount of memory required in an embedded system?

How to Answer
Answer Example

Organizations hire employees for one of three reasons: to help them make money, save money, or save time. During an interview, you will be asked how you will accomplish this for the organization. Having creative ideas to accomplish some of these objectives will distinguish you from other candidates and convince the hiring manager to bring you on board. Before the interview, you should research the organization to understand its challenges and have a few ideas about how your work can help them overcome these.

"There are several different techniques you can use to reduce the amount of memory required by an embedded system. Some of these include factoring your code, only returning values when they are necessary, making a large number of calls to a small function as opposed to a small number of calls to a larger function, and using as many local variables as you can, reducing the number of system calls and memory usage. All of these techniques work, so I use the ones that are most applicable to the function of the device and the type of code I am writing."
