Challenged when given the job (5,2)

I believe the answer is:

taken on

I believe this clue is a double definition.

'challenged' is the first definition.
(to challenge or fight someone is to take them on)

'given the job' is the second definition.
(to take someone on is to hire them)

'when' is the link.

(Another definition for taken on that I've seen is " Hired".)

I've seen this clue in The Guardian.
