You can often identify the type of question you're being asked by how the interviewer at Salesforce asks it. When you hear a phrase such as 'walk me through the steps...,' you know that this is an operational question. The best way to respond to this sort of question is to break down the process into individual steps and briefly describe each one. The interviewer will likely ask you a follow-up question so they can better understand your methodology, so come prepared with a few examples. It is also a good idea to follow up your answer with a confirming question. Getting the interviewer to answer questions helps them develop a positive impression of you.
