Deadlock
Also written as Lock Contention, Livelock
Two processes each holding something the other needs, so neither can continue — the system stops without crashing.
Think of it like
Two people in a narrow corridor, each stepping aside in the same direction, forever.
Junior or senior?
Strong signal when someone has actually resolved one, usually at the database level.
Senior sounds like
Talks about lock ordering or timeouts.
Ask them
“Have you diagnosed a deadlock? What was holding what?”
