One of the biggest lightbulb moments for me while doing interview prep with one of the big name companies was how to answer the more vague or generic questions. They're just a trampoline to launch into a STAR type scenario without specifically asking you "tell me about a time...". Before prep, I would answer questions like "how do you deal with failure?" or "what does customer service mean to you" either with a one sentence answer or rambling in a circular pattern for way to long. Instead, they showed me how to keep my one sentence answer and follow with "like that one time..." launching into a story. I also learned that you only need a handful of TMAAT stories, covering a series of generic topics. It's impossible to have one for every possible question, but the trick is recognizing what topic that question is trying to probe, and give the story on that topic, even if in your head you would have worded the question differently. For me the prep was worth its weight in gold. It allowed me to settle my thoughts and go in with much more confidence than if I'd just tried to wing it.
