SAP Software Engineer Interview Questions

I would use either a subquery, a window function, or a distinct sort depending on the database and the exact requirement. The key is to handle duplicates correctly and make the logic clear. Strong answers also mention how to adapt the query for department-level grouping.

I would focus on generating unique short codes, storing the mapping efficiently, and making redirects fast. Then I would think about collisions, scaling, analytics, and how to keep the service reliable under heavy use. Good design balances simplicity with long-term scalability.

I would make the upload reliable by supporting chunking, retries, idempotency, and clear progress feedback. Then I would think about validation, storage, and how to recover from partial failures. The best answer shows awareness of both user experience and backend robustness.

I would separate event ingestion, stream processing, aggregation, and dashboard reads so each part can scale independently. Then I would use caching and precomputed views where needed to keep the UI responsive. A strong answer shows that freshness and performance have to be balanced carefully.

I would start by understanding the core business entities, the integrations involved, and the reliability requirements. Then I would design around data integrity, permissions, and auditability because enterprise systems often need strong trust guarantees. Good answers show that you think beyond just the code.
