Everyone is too busy for true mentorship, not in the sense of hand holding and explaining everything to you, but if you're stuck and need help you will have to figure it out on your own 95% of the time. The onboarding process is brutal. The goal is to get you situated with what type of work you will be doing, but you also do real, very hard work at the same time as maintaining onboarding projects. The onboarding projects aren't simple either, they take a lot of time and there is a hidden expectation that you will just literally work a lot of hours your entire time there (50-55 hours/week). The approach is really dropping you in the deep end and hoping you survive. The phrase "hire liberally, fire quickly" is used to describe how they view new hires. They don't really keep that many people longer than 4-6 months either due to firing or quitting out of stress. Cybersecurity is hard, this place makes it harder. In all fairness, I think these are typical struggles many startups/small businesses have in the tech world and in order to succeed you should have decent experience to begin with.
