Salesforce Member of Technical Staff(MTS) interview questions

First round with senior manager, after that there will a hacker rank 90min test, third round will be a technical round, the question is very basic but the interviewer was having zero knowledge on programming and framework. He was forcing me to write program in a language he knows and not able to explain the problems. I asked him multiple times the output of program but he was not able to explain it. He had 13 years of experience in which he was working as consultant for 11 years in service based company. I am very happy that I am not going to work under this incompetent senior. This is really big problem with most of the MNCs. "The incompetent egoistic employees".
