My interview as the representative of the entry-level employees was published in the spring edition of the company newsletter.
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means publish so the verb vocab version is to be published. Books can be published, magazines can be published, and I guess even your gross blog posts get published too.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:
"Hey, were you able to be published yet?" someone asks, and the answer is always NO (の)! It's never your time to get published. The answer is always no... because no one likes (sniff) what you write (sob).
