The short version
Why the Full Stack Engineer interview is hard
Full stack interviews look for breadth that is real rather than claimed, plus at least one area where you go genuinely deep. The recurring test is whether you can follow a single feature from the interface all the way to the database and back.
What to expect
The rounds you should rehearse
End-to-end tracing
following one user action through every layer that serves it.
The seam between layers
API contracts, and where responsibility should sit.
A declared depth
one area you can be pushed hard on without running out of answers.
Avoid these
The mistakes that quietly sink candidates
Claiming even expertise everywhere, which usually reads as shallow in all directions.
Being unable to say where a bug lives when the symptom appears in the interface.
Neglecting the database, which is the layer full stack candidates most often skim.
