There are many different processes you can use as a firmware engineer. Some of these will be dependent on the type of system you design, while others may be a personal preference. In either case, when you were asked about specific processes, describe the steps using easy-to-understand, non-technical language. If you do not use the process you are being asked about, provide the interviewer with a reasonable alternative that can be used and is just as efficient.

"When storing data from a receiver line, the first command I use stops the transmitter side from sending additional data. Commands that accomplished this include X/ON and X/OFF or RTS and CTS. I then set up a queue to store and prioritize the data. An alternative to this is using a ring-buffer. Both of these data structures establish a queue and are relatively easy to set up."
