Salesforce Interview Question Bank
Salesforce's loop is bank-driven: a small set of coding prompts (LFU Cache, Flatten JSON, linked-list dedup, frontend curry + traffic light, OA HackerRank classics) and one signature system design (Coffee Ordering, with its SQL follow-ups) cover the bulk of recent rounds. Down-leveling at offer time is common — the HM screen and behavioural depth materially shape the final level, often more than coding correctness alone.
