The first step was a technical phone screen with an engineer.

The engineer wasn't very warm to speak with and wasn't helpful at all during the interview. He asked two questions about chess pieces and how many steps it takes to go from one location on a chessboard to another.

The second part of the question was particularly difficult. Though I explained the right approach, it was tough being able to code it up with someone watching. Not to mention, he was silent the whole time, and I wasn't even sure if he was paying attention or not.

Not surprisingly, I didn't move on, but I didn't care anymore. The interview left a bad taste in my mouth.

What is the smallest amount of moves it takes a king to move from its starting location to a different location on the chessboard?

What is the smallest amount of moves it takes a king to move from its starting location to a different location on the chessboard when there are guards? There can be any number of guards placed on the chessboard, which prevents the king from going on that spot.
