There is not an exact antonym for every word. That said, it depends on what you think of as an opposite in this case. Is the opposite of examiner the one being examined? The test-taker or the examinee could be the antonym. On the other hand, what if there is no test taker... what if the examiner is just examining backpacks as they come off the assembly line? The CEO could be the opposite, if he is on the bottom rung of the company, and the CEO is at the top. ... Just an example, but language isn't always "black and white." :)
