What Is LL in Interview Slang?

Full Definition

LL is an overloaded acronym in interview-prep contexts. The most common meanings: (1) Lower Level — a loop calibrated for junior candidates (L3, L4 in Google parlance; SDE1 at Amazon; E3 at Meta), with easier coding problems and less depth expected on system design. (2) Linked List — the data structure, in the context of LeetCode problem categorization. (3) Leadership — sometimes used in Amazon contexts as a counterpoint to LP (Leadership Principles). The disambiguation comes from context: 'I got LL'd' = the loop was calibrated lower than expected (often the recruiter dropped the candidate from L5 to L4 mid-process), 'LL problems' = linked list problems, 'LL questions' = leadership/behavioral questions. Candidates should ask the recruiter directly which level they are being interviewed at, since 'LL' can also mean a downlevel happened (a quiet shift from the originally agreed level, often with corresponding lower comp).
