Here's the revised version with that addition:
"The whole interview process was a complete disaster. First, I was contacted for one position, only to be interviewed for something completely different—which is frustrating but maybe not entirely unexpected. Then, they had us participate in a poorly organized group interview, where we were asked irrelevant questions that had little to do with the role. After that, they had us complete a so-called 'exam,' which was just ridiculous: correcting grammatical errors in a passage and, bizarrely, writing a poem! As if that weren’t enough, I was then called in for yet another interview, only to be informed that I'd need to complete a one-day trial afterward—all this just to make calls. The entire process was disjointed, unnecessary, and incredibly frustrating."
