Amadeus interview questions

I got call from a consultancy firm, scheduled my interview on weekend for UI developer. There was two technical round and one managerial round. In first round he asked all about javascript and few HTML questions, second round was mostly on Angular 1.5 and few Angular 2 concepts. All went well and they told me that i will be getting a call for Director round. Next week i was called for another Technical round followed by Director round, in this tech round she asked me only OOJS and advanced Javascript programs, you have to be good in Array and Objects(Prototype Inheritance). After 7/10 days i was called for HR round and they processed my offer after another one week

The interview consisted of 4 rounds 1. Aptitude Round It had questions related to data interpretation (from charts) and reading comprehension. Verbal was easy but data interpretation was confusing. 2. Technical Interview : During technical interview,I was asked questions about data structures, time complexity, OOPS. 2 programming questions, which were relatively easier (than any hackerrank contests) and 1 analytical question which I think didn't have any concrete answer, but was just about the approach. 3. Managerial Round. In this round, I was asked about my favourite topics / technology. I answered as Machine Learning, and was asked to explain a concept regarding Regression. Other than that there was 1 puzzle which wasn't that hard. 4. HR round: HR round was shortest for me. I was asked about my life till now, my worst day in college and few other things (don't remember)
