AT&T vs T-Systems

I have two offers and would appreciate insights from anyone who has worked with or closely knows these organizations:

1. AT&T – Sr. Associate, Cloud/Linux Infrastructure Support (Chief Data Office)

   • Likely shift-based support role

2. T-Systems – Consultant, Azure Cloud Engineer – Ops Focus

   • Hands-on Azure infra, automation, IaC (ARM/Terraform)
   • Deutsche Telekom group

Looking for opinions on:

• Work-life balance
• Growth opportunities in cloud/DevOps
• Long-term tech exposure
• Work culture and stability

Would love to hear from current or ex-employees. Thanks in advance!
