Too good to be true

Pros

A lot of good perks, friendly staff, great supervisors

Cons

Left my old job to come here because of the hybrid schedule having little kids and not being able to afford child care made life work balance much easier now they are trying to change that and stream like to full time in office which is earth shattering for a lot of employees. Other departments work home 5 days a week and continue to reap that benefit.

We understand that shifts in workplace expectations can be challenging, and we’re committed to supporting our employees through this transition. Our move to a 4:1 in-office schedule reflects our belief in the power of in-person collaboration to drive innovation, connection, and long-term success. While the policy will remain in place, we’re actively working on ways to make the in-office experience as productive and positive as possible, and we welcome ongoing dialogue to help us do that well. As a newer team member, your fresh perspective is particularly valuable as we shape our workplace culture.

Pros

Good PTO and benefits but that is about it.

Cons

The Okta and directory team is not a bright team at all. I pulled these guys out of a big whole they dug themselves into by not knowing any form of automation language and trying to manage over 25k users and computers manually. Whole year I built solutions for which I never got credit for, the team, specifically the manager were intimidated by my skills so every time I did something amazing they took credit for it telling everyone else outside of the team that it was their idea and code but these guys were not able to write 2 lines of code themselves. No shame no intellect and the manager is complete idiot with no guts to learn something that way he can tell is his idea instead of stealing it away from somebody else.
