The process starts from online agent consultancy. You cannot expect any positive from them. They will randomly pick you from there. After that, you will be directing to HDFC Office. You cannot expect what questions they are going to ask. Its completely related to how customer friendly you are. For me, they told me to explain about my watch, its feature and its brand name. Also thorough study about the HDFC history( share value etc). After that 3 more rounds. That will happen on the same day itself. So total 5 rounds interview.
