Read the text message from a friend who just quit their summer job and select the correct option to fill in the blanks.

"I finally quit! I was completely _____ the endless paperwork. It was the most _____ job I've ever had."

The correct answer is bored with / boring.

When expressing that you have lost interest in something, the correct structure is bored with (or sometimes bored by / bored of in informal speech, but with is the standard preposition).

The job itself is the cause of the feeling, so it is described using the present participle adjective: boring.
