Databricks Software Engineer Interview Experience — Game Logic, Referral Credits, and Chat Design

The report describes two coding sessions and a chat-system design discussion in a Databricks onsite. One coding exercise involved a turn-based board game, including player switching, board output, and correctly ending wins or draws. Its follow-up introduced automated play.

The other exercise tracked account credits associated with referrals, queried accounts meeting a threshold, and extended credit handling to indirect referral relationships. The design conversation focused on interfaces, database structure, and basic interaction flows, with little discussion of scaling. The account provides the tasks and their extensions but does not describe the applicant’s implementation, performance feedback, or hiring outcome.
