Altis Infonet Node Js Developer interview questions

I had only the first round of interview so far and it was a good experience. It was a face to face interview(no machine coding involved). You get asked about the basics of the coding language you are going to work with. A few advanced topics as well and also some questions on how you would solve a particular coding problem(which wasn't too difficult). Overall it last around 30 to 40 mins
