How is D.E. Shaw?

Any idea about how is D.E. Shaw for a fresher. In terms of WLB, work culture, Salary, Hikes and overall. I am an average person, will I be able to survive there.

Looking at recent layoffs in other companies, I am really worried about how companies treat employees, laying them off if they don't perform well. Or even without that.

Are there any layoffs happening?
