QUESTION 29 OF 30

What is the number of ECUs that can be connected in a 40 meter CAN Cable, and do they need to be equally spaced?

This may seem like a pretty basic question, but only qualified CAN developers will be able to answer it. It is also an example of a close-ended question with a very specific answer. Interviewers will ask this early in the interview to qualify of your capabilities so they know if they can move on to more difficult and challenging questions.

When asked a close-ended question, provide the interviewer with the answer and then be quiet. They will either ask you a follow-up question or move on to their next one. This is a great example of less being more. You can only get this question wrong by expanding your answer and providing details that the interviewer isn't expecting, which may cause them to challenge the answer by asking you a more detailed follow-up question.

"The maximum number of ECUs that can be connected in a 40 meter CAN cable is 30, and they don't need to be evenly spaced."
