I realized I've been doing everything wrong! From soft skills to answering questions. They are very personal, and they teach you how to create a killer "tell me about yourself" answer (because that question is almost guaranteed). They teach you how to answer questions to make yourself look like a future asset to the squadron. They teach you methods on answering the questions, and you have 2 video mock interviews which they tell you on what you need to improve on.
I was just like you, wondering dropping hundreds is worth it, because I was already broke from flight lessons. But it was my best investment ever. If you're not willing to give it your absolute everything to get a slot, especially during these extremely competitive times, you will regret it when it's too late.
