1. HR calls you do all screening and checks for which role you will be fit in for eg: UI Consultant, Senior UI Con… or Lead UI Con… 2. Very nicely she explained me the entire process as in through what all process and rounds I’ll go through. She shared one GitHub repo of plain “js/html/css” project with me and asked to go through it. 3. She then told me to do homework and identify the mistakes in code, look for what better approach we can think of in this code, code cleanliness and everything. I then in couple of days let HR know to set up my 1st technical round as pair coding round. 4. My first round went really well where interviewer was very knowledgeable & strongly experienced. So as mentioned by HR very firstly he asked me tell me about the code what you noticed. I explained him completely about what the app was about, about 3-4 util functions those were there in the code, I suggested one performance betterment and also since I ran the code in IDE we were looking at it while I was explaining. 1. So there was one button with functionally say showing data of 30 days, I was told to implement the similar functionality with another button where you show data of 24 hours. Also there was no click event attached to already present button, you are supposed to attach the listeners to both the buttons and toggle. 2. Very importantly this all as plain JS and html code. After I implemented the mentioned task he did keep on adding various cases, we were having very healthy technical discussion on functional programming, js design patterns etc. 3. Then he asked me the output of few programs, where he shared his screen and was showing me multiple codes. 4. He was very polite and modest to help me understand each requirement and also sometimes guiding me in thinking towards the solution. 5. After almost 90 minutes of discussion, this round went very well for me. 5. HR called up after a day or so and briefed me about the detailed feedback by interviewer of 1st round and then she went on discussing about upcoming round which was technical too with 2 interviewers in one call. She gave me detailed information about what is expected and how you should drive the conversation. 6. So in 2nd round the conversation started with my current project. 1. They literally deep dived in all the aspects, TDD, why this tech stack, what all things you use, CI/CD, business logics, why you implemented this functionality like this only why not other way, don’t you find the tech stack is little odd that you have chosen, then about css I mentioned we use sass where they deep dived in what is preprocessors, mixins, variables, then difference between css and sass variables, how you do theme config of entire app, what is shadow DOM and what’s it’s purpose of using. Trust me this all went well for me. 2. Now they gave me one requirement, which you can say was an entire web application type requirement. They asked me to explain the work flow. I tried my best to explain and they were satisfied. Then they said to implement it and I was expecting what part of it you want me to write code for I’ll do but they said no whatever you explained do it. Though it was very very broad requirement I started writing and app from scratch then one of them realised and asked me let’s switch to another question. 3. They asked me to about local storage and all the other storage options in browser. 4. They asked me to write the Promise polyfill which I did. 5. Then they asked me to write one snippet and what will be the output. 6. Same after discussion of almost 90 minutes we wrapped up and I felt it all went well. 7. I haven’t heard back for 2 days so I went on asking and then I was told that feedback of 2nd round was 50-50. You very well explained your current project and all tech stack used, TDD etc was all good. But the work flow question that was asked you very well explained theoretically but you didn’t practically implemented it. Rest other fundamental JS were very strong. So finally she said I’ll try from my side to push your candidature but you consider it NO. Though I kept my points but I don’t know what impact it will make. Rough day for me :) 
So entirely it was very fair and tech savvy experience. Was very keen to get selected but nevertheless will prepare more and bounce back someday ;)
