Company: Discord
Role: Software Engineer
Category: Software Engineering Fundamentals
Difficulty: hard
Interview Round: HR Screen
## Interview prompts (practical engineering)
1. **What databases have you worked with?**
- Which engines (SQL/NoSQL), what scale, and what features you used (replication, partitioning, transactions, backups, migrations).
2. **How do you debug race conditions?**
- Describe your approach to reproducing, isolating, and fixing concurrency bugs.
3. **How do you use AI in your coding workflow?**
- Where does it help (design, implementation, tests, refactors, incident response)?
4. **How do you verify AI-generated code?**
- What checks do you apply before shipping (correctness, performance, security, operational safety)?
Quick Answer: This question evaluates a candidate's practical database engineering knowledge, concurrency debugging skills, and ability to integrate and verify AI-assisted code, covering competencies in database systems, race condition diagnosis, and code correctness and security checks.
