Baby-steps progression exercise. Implement one-dimensional tree of strings - animal types. Animal might be a sub-type of another animal. At first you start just implementing the UI and offsets without using spaces, then move on to extracting the data to json file and parsing it. Then you add an Input next to an Animal name, that allows new animal to be added as a Sub-Type in runtime. During the followup they asked to add ability to remove the animal from the tree, removing any of it’s sub-types as well.

started with phone screen, it was easy. I did great in all the 6 interviews except one interview where the interviewer asked me to write code about graph / tree. I explained topological sort but she didn't know what Topological sort and Graph Indegree / outdegree were, she had a laptop which she kept typing in, i did excellent in my other interviews but this one she kept pushing me to the solution she had in the laptop which she thought was the most optimal solution. The company is great but I kinda felt weird where people with 14 years of experience are graded by people with 2 years of experience. I would recommend increasing the coding round and decreasing the general sessions, this way you can't get rejected by one bad interviewer.
