The first code challenge was about matching different tags that a user could add in a multi-select list and unifying them if they belonged to the same group. I thought it required an inverted index, so I over-complicated the solution. A simpler approach using multiple loops would actually have been more effective. The second challenge was about React and involved building a simple table, then progressively adding features like filters, sorting, etc. For the cultural-type interviews, the questions were about previous projects and how I handled certain scenarios—for example, how I deal with situations where I disagree with my manager. For the system-design interview, I was asked to design a dashboard that supports multiple widgets.
