Has this ever happened to anyone?

I can speak from the other side. [Formation.dev](https://Formation.dev) (I am co-founder) isn't a bootcamp but do turn people down who want to join us (sometimes really really want to join). The typical reasons we have turned people down are: 1. Misalignment of goals. If you want something out of your training that we don't think we can achieve with you, we won't move forward. We would only take someone we are confident we can help achieve a top tier company role, because we commit to training you all the way until get a happy result. 2. Not at the technical skill bar. We have a fair technical assessment to help us assess starting data structure and algorithms skills, if you aren't at the bar, or we don't see enough potential, then we will typically not move forward. In this case, we would want you to join in the future though if you can get to the skill bar necessary. 3. Other reasons you will not pass an interview. Our recruiters have worked at top tier companies for anywhere from 3 to 10 years and they have worked with thousands of candidates there. So if there is something about your background, skills, or concerning answers to questions that we don't think we can help you address to get placed, we might not move forward. For example, if you lied about something, cheated on assessments, provided false information, harassed recruiters or employees, etc... Typical reasons why most companies wouldn't move forward with someone.
