Dassault Systèmes Senior Software Engineer interview questions

I gave 3 rounds of Interview(2 Technical, 1 Managerial) at 3ds. 1st Interview done on the core Javascript and ES6 features. 2nd Interview done on the Basic CSS3 and HTML5. 3rd Interview is managerial round, In this Round discussed about the Project which worked on the Previous organization.

1st round was online technical which consists of programming and database. After appearing this round I got a call from them after 3.5 months that I cleared the round. Then they schedule my interview to some date and time and when I waited for the interview on the same. They didn't show up. afterward, I got a call that my slot was taken by someone else. Then after allocating the next date and time, I attended the same. Their technical interview guy came up and started firing up the question like writing a program without using an inbuilt method and without using any kind of internet search or referring documentation. I told him that without using the inbuilt method then I need to refer to its official documentation to check the syntax because that's how I solve problems and also I am bad with remembering things or else I can show you the pseudocode or Logical flow to solve that problem. But he doesn't want that and he goes to the next question which was also almost the same. I was having almost 5 years of experience and this guy was very rude to me and his interview is very non-interactive. He was taking this interview in a very bossy style. The guy seriously needs to work on his interviewing skills and examining the candidate's potential. By having a healthy conversation with that guy I decided to not go further with this interview and this company.
