Then make each item clickable to display/ hide a subtext after clicking on headings. Lastly, keep and display a count of text items clicked. Round 2- First hour(1/5) was again React coding round, where you are given a UI component for empty and occupied parking spot and you have to reuse the UI components to render a parking lot. Then make the parking spot clickable to park/ unpark a car in spot. Lastly, each parking spot has a cost associated with it which we had to add and display based on number of cars parked in the lot Second hour(2/5) - Plain javascript coding with easy array based algorithmic question. Third Hour(3/5) - Review their mobile app and make suggestion on how to improve/ test it. Fourth Hour(4/5) - Design their mobile app from scratch. What libraries will you use.
