Real, anonymized candidate journeys from recent (2025) Oracle interview loops — round by round, including what was asked, how the candidate approached it, and the outcome.
One complete journey, start to finish
Round 1 — Pre-screening
Java fundamentals: exceptions, immutable class design, deadlocks, SOLID principles, factory and abstract-factory patterns, and Spring Boot basics.
Round 2 — Hiring Manager Loop
System design for a ticket-booking-style service: requirement gathering, API design, and a high-level design diagram.
Round 3 — DSA Loop
Converting integers to Roman numerals, with a focus on making the symbol-mapping design extensible.
Round 4 — Behavioral Loop
Current role responsibilities, features implemented, and how disagreements with senior colleagues were handled.
Round 5 — DSA Loop
Threading concepts (producer-consumer with wait/notify), immutability, singleton pattern, linked-list cycle detection, and summing the deepest-level nodes of a binary tree.
Key takeaway: Watch out for interviewers who seem unusually friendly — it may not correlate with how consistently they evaluate the answers; this candidate covered Java fundamentals, system design, DSA, and behavioral across five full rounds but was ultimately not selected.
