KPMG Audit Intern interview questions

During the last stage of the interview, the department head was asking various questions relevant to the position. However, one of the last question was a bit strange to say the least that left me confused and curious whether I would be willing to work for a person that assigns tasks or provide feedback using random allegories: "A woman came to the market to sell eggs. The first customer bought half of her eggs and a half of an egg. The second customer bought half of the remaining eggs and a half of an egg. The third customer only bought one egg. After that, the woman had no eggs in stock. How many eggs did she bring with her to the market?"

Tell me about a way you recovered from hardship, leadership, etc.
