It’s was one of the best interviews I attended. Interviewer started with my self rating on my skill sets . JavaScript, HTML5, CSS and on ReactJs. Interviewer was focused on what he wanted to ask and could explain me the question well. Started with JavaScript. Basic to moderate questions and some tough questions on asynchronous JavaScript . He tested me on my understanding of JavaScript of design patterns , drew me a situations and how to implement the design pattern to achieve solution and so on. Ask some basic memory management . HTML5 - all Symantics, audio video canvas, geolocationapi etc and much more I don’t remember now :) Css preprocessor , mixins, functions var etc ReactJs, solid understanding , ReactJs Architecture, state management, props , life cycle methods, high order components , Redux architecture and workflow etc Overall , solid understanding on UI front end technologies & standards. I could answer some and couldn’t some. However, interviewer was kind and explained me whatever I asked in the end of the interview. Seems if I get to work with such ppl surely one would learn a lot of things. Not sure if he told his name I asked , not sure if I should share here. I guess he told his name was Asif zaafar. I couldn’t thank him on interview so he deserve a review here. Great company cdk and professional HR.
