Java threading basics appear in almost every fresher interview — even when the role is fullstack. Interviewers want to know that you understand the difference between a process and a thread, can create a thread two ways (extending Thread vs implementing Runnable), know the six thread lifecycle states, and have a basic grasp of synchronized and visibility problems. This module stops before advanced concurrency (locks, CompletableFuture chains) — just the foundation every fresher needs to answer threading questions without going blank.
