12 hour shifts, likely forced to do nights as condition of your hire.
Very very poor leadership, no one in mid-level management or below is willing to speak truth to power or advocate for shift employees.
High performers get either pitiful or no meaningful recognition while mistake-prone or willfully negligent employees are allowed to breeze by.
Even if the company has strong profits, you are not guaranteed a raise, and if you get one it will be pitiful and barely eek out inflation.
Management is very tone deaf and usually will yell for things to be done without bothering to understand underlying issues.
Also, for a billion dollar company they are very willing and even pleased to have run-down and out of date accommodations and facilities. The place looks and feels forgotten, as will you eventually on your computer!
Overall: Do not take this job for longer than 2 years if you have literally any other career prospects, take it and while you have it just use it as a security to interview like mad and negotiate hard for a good job you want elsewhere.
