Pros
The industry itself is rather interesting.
Cons
Work-home life balance was terrible. I was always told during every holiday or day off that I needed to take my phone with me at all times. To be clear I was not a senior level and I was nearly always messaged/called on my days off with questions that were not important. I've also never worked in a business that has senior management speak to employees the way that OpSec's do, coming from the very top. Due to this, it meant a lot of time and energy went towards focusing on how you would pitch things to those at senior level and manage them, rather than coming up with creative solutions to problems or putting your best work into your actual role. There is no culture of supporting employees or encouraging meaningful growth. Diversity was also terrible.
