The longest interview I have attended to date. Most of the questions were from my resume about past projects and a couple of basic questions about linked lists (insert, delete).

Hypothetical questions included:

• What technology would you use if you had to count the occurrence of all the words from Wikipedia within a day?
• What kind of interaction would you have if you wanted to recommend products to a user?

The interview was unusual in the manner it was conducted. The entire time, about 3-4 hours, was about the resume content.

A question on what kind of interaction you would have with a user if you want to recommend products.
