The interviews were supposed to begin with an advanced JavaScript and coding round. However, the interviewer was unaware of which round it was. It was later confirmed that they'll be taking up Machine coding in React. The interviewer arrived 5 minutes late and spent an additional 5 minutes on introductions and resume-related questions. The problem provided was to design a calendar-based app with the ability to switch between weekly and monthly views. Additionally, it should support slot accommodations in between similar to google calendar. Both the interviewer and I knew that completing the task within an hour was unrealistic. I attempted to check online resources like MDN for date constructs and prototypes, but it wasn't allowed. In the last 10 minutes, I was informed that I needed to take a different approach to building the calendar, as they required the monthly-to-weekly view switch to happen within the exact same UI.
