I worked closely for years with program recruiters for tech bootcamps. Sometimes they take awhile to follow-up on applications. I remember learners in my classroom telling me that they applied up to 3 times over the course of 9 months before they got a response.
At that time, I worked closely with the program recruiters. They were completely overwhelmed with applications. You may have to follow-up with someone (if you haven’t already). Find someone to reach out to via LinkedIn, and see what’s the status with your application.
I know Vendition is a for-profit model, but they may have the same issue.
If you’re still interested in a tech sales training, take a look at OneTen and Aspireship (if you haven’t already). They’re free to get in, but OneTen won’t accept you if you already have a college degree. Last time I checked, neither one will pay you while you train. Aspireship won’t take a percentage of your income after you graduate. I can’t confirm if that’s the same for OneTen. Hope this helps.
