The interview contains a total of 4 rounds: machine coding, psds, ui tech and product design. In the machine coding round I was asked to build an application based on the problem they provided. The catch here is not to use any JS frameworks, only vanilla JS has to be used. In the 2nd round which is problem solving and data structures round, I was asked few questions based on stack, greedy algorithm and dynamic programming. The 3rd round is the UI Tech round in which the domain knowledge is checked. Mostly questions were on Javascript and some CSS. I didn't get through 3rd round although the interview went great. However, overall experience was positive and got to learn a lot.
