Telephone interview literature - what's this?

[Kong]

Hi chaps

Telephone interview today for a job with the Environment Agency customer service department. I believe the interview will contain technical exercises.

They have just sent me this picture which I will need to answer one of the questions:



Any ideas what it could be about?

It's a dance move, step to the right, 1-2, and get down.

Ahhhhh, turns out I had to describe the picture to the interviewer on the phone, makes sense now
