How do LIN and CAN protocols differ?
This may be a follow-up to a question you were asked earlier in the interview. Interviewers ask follow-up questions when they need additional information or want to explore the topic in more depth. They may ask a follow-up question immediately after the initial question or later in the interview. If asked later in the interview, they may be correlating your answers to make sure you are being consistent and not fabricating the information you are providing.
Once you recognize a question as a follow-up, it is okay to elaborate on your answer. By asking a follow-up question, the interviewer has already indicated they need more information on the topic or want to explore it in more depth. This provides you with permission to expand your answer and include details not provided during your initial response. However, try not to embellish too much or provide content for the sake of content. Interviewers always appreciate brevity and directness.
"The main differences between LIN and CAN protocols are their costs, capabilities, and applications. The LIN protocol provides vehicles with a low-cost, short-distance, and low-speed network. LIN operates within a CAN environment but doesn't require the high data rate and wider bandwidth or the higher cost of CAN. Working together, these protocols enable developers to create automotive systems that are both effective and efficient."
