BlueOptima Senior Software Engineer interview questions

I was interviewed at blue optima everything got scheduled in one week. First an online coding test was there consisting of two questions . I believe this is irrelevant at first because experience developers are business driven. So design-pattern, framework ,architecture etc is mindset of experience developers. While these coding challenges are for fresher's and coders who belong to a specific category like hackerrank, leetcode etc. There is a difference between a business driven developer and coding challenge coder. After this rubbish online exam was done I had given an interview where basic questions were asked about my day to day activities and overall exp. After this I was asked two question about 1. immutable object in java and how to make one. 2. multithreading in java and atomic operations. Both of these questions were simple so I gave well defined explanations with examples. Well the interviewer also told me that he had gone thoroughly in my profile before start of interview. And he was keen to have a developer who has good knowledge of spring-boot framework, functional java, and multithreading concepts. While I was also expecting few questions on same technologies as I am experienced in all of them. Like functional java questions about lambda expressions ,streams etc. But my interview was merely a joke and waste of my time and knowledge as I believe the interviewer didn't had that kind of knowledge to interview someone experience like me.
