One of the key skills candidates should develop for interviews is interpreting the interviewers' questions and responding appropriately. Not only do the questions indicate how the interviewer is expecting you to respond, but their body language during your response may provide some additional information. If the interviewer begins to fidget, looks at their notes, or seems distracted, this indicates that you are providing too much information. Conversely, if they ask follow-up questions after each of your answers, they are indicating your answers are too brief and you need to elaborate more.

"During data transmission, bit stuffing is the insertion of non-information bits into data. Since CAN uses a non-return-to-zero protocol, bit stuffing typically occurs after the fifth bit. The purpose of bit stuffing is to provide a terminus for the signal so the receiver can resynchronize with the transmitter before clock discrepancies between the nodes occur. In CAN, the transmitter transmits a maximum of five consecutive bits with the same value. After five bits with the same value of either zero or one, the transmitter inserts a stuff bit with the opposite state to resynchronize to the transmitter's clock."
