Every company interviews differently.
Prep for yours.
Some let you use AI in a coding round; most still ban it. Some go deep on transformers, others on system design. See each company’s rounds, its AI rules and what it weighs most. Pick one when you build your plan, and your plan leans toward what it tests.
