First, I had a written test at home to implement a function that validates user input for their Wordy game. I did it over the weekend and submitted it. Then, I was invited for an on-site interview. The on-site interview took four hours.

The first hour involved writing a function to calculate the price of coffee in a coffee machine, depending on size (small, large, etc.) and the selection of condiments (sugar, milk, etc.). I had to program this with the interviewer sitting behind me.

The second hour presented the same problem, but the conditions became slightly more complex: now the price of condiments depended on the coffee cup size.

During the third hour, I was asked to fix some issues in their artificially incorrect implementation of a Set class.

Throughout this time, I practically didn't communicate with the interviewers; they just sat behind me and watched what I was doing.

The last hour was a conversation with the project manager. It was a free-flowing discussion about my experience.

At the end, I didn't get an offer, though I don't exactly understand the reason. I was told that the team was satisfied with my technical skills but didn't feel that I was excited (eager) enough to work for their company, which sounds really weird to me.

Write a function that calculates the price of a cup of coffee. The price of condiments depends on the size of the coffee cup.

For example, milk costs:

• 10 cents for a small cup
• 15 cents for a medium cup
• 20 cents for a large cup
