Decent Flexibility, But It Really Depends
It's a big company, so experiences vary, but generally, there's some decent work flexibility here. You'll find a pretty standard hybrid model, which is okay, but it's not without its quirks.
The hybrid model is solid; I'm in the Austin, Texas office a couple days a week. For us in industrial software development, it's a good setup to collaborate but also focus. Most managers are pretty understanding about WFH days when needed, which is a plus.
Work flexibility really depends on your direct manager, which can be tough. Some teams have more rigid core hours for their Software Engineer roles than others. It's definitely not fully remote, so don't expect that if you're looking for it.
Try to standardize work-from-home policies across departments. It'd help a lot with consistency and employee morale, especially regarding core hours.
