Overall, I liked the interview, but I was filtered by the assessment test. It was very confusing, with lots of irrelevant brain teasers. Be sure to do the coding part first, but it should be easy if you have experience in coding.

A man walks into a store and sees an item. He says, "How much for one?" The cashier answers, "20 cents." The man buys it.

Later, another man walks in and sees the item. He says he wants 20, to which the cashier replies, "40 cents."

After that, a third man walks in and sees the item. He says he wants 120, and the cashier says, "60 cents."

What is it?
