Strong OOP design, arrays, and leadership-principle-driven solutions. Expect systems design questions and large-scale data handling.
Amazon's technical interviews combine rigorous data structures and systems coding with a heavy focus on the 16 Amazon Leadership Principles (such as Customer Obsession, Ownership, and Bias for Action). Candidates must write production-ready Python code while explaining trade-offs.
Amazon evaluates object-oriented design, clean modular function signatures, and error handling. Python candidates should master array manipulation, heap queues, stack state machines, and hash table lookups.
AWS and Data Analyst roles heavily test multi-table INNER/LEFT JOINs, GROUP BY aggregations with HAVING clauses, subqueries, and window functions for customer transaction analytics.
