MongoDB Principle Application Delivery Consultant interview questions

1. Why java is similar to javascript? 2. If you're a java resource then please create a project using javascript because both are used for same purpose? ....I didn't agree but didn't want to argue. 3. what is the difference between outer join & outer most join?.......I just told him that I never heard such thing in SQL. 4. why kafka cannot handle load? ... I told him it can but he didn't agree 5. why jvm is platform independent?.. I told him that java is platform independent not jvm Note.... All these questions are invalid. Although, the interviewer asked these questions , I told him that these questions don't make any sense. So he later said , sorry I am not a java resource but I am learning and then he just rejected me by giving feedback that I am not good in javascript although it was supposed to be a backend interview.
