Absolutely. Here are some mock interview questions that could come up:

• Behavioral: Tell me about a time when you had to debug or optimize a complex distributed system component. What approach did you take, and what was the outcome?
• Behavioral: Describe an experience where you had to collaborate with cross-functional teams spread across different locations. How did you ensure effective communication and delivery?
• Behavioral: Give an example of when you faced conflicting priorities between reliability and performance in a system you worked on. How did you resolve this tension?
• Behavioral: Talk about a situation where you had to quickly learn and apply a new technology or concept to solve a pressing problem. How did you approach this learning curve?
• Technical: Can you explain the trade-offs inherent in distributed systems design, particularly related to the CAP theorem and its impact on Cassandra?
• Technical: How would you design a quota and rate limiting mechanism for a multi-tenant distributed database environment?
• Technical: What strategies would you employ for fault injection testing in a high-throughput storage system to ensure robustness?
• Technical: Describe your experience optimizing Java-based systems for performance, particularly in a storage or database context.
• Situational: Imagine a scenario where an internal platform service complains of high latency affecting their critical workflows. How would you investigate and address this issue in the Cassandra infrastructure?
• Situational: You discover a subtle bug in the replication logic affecting data consistency across datacenters. What steps would you take to diagnose, fix, and validate your solution without disrupting live services?
• Situational: Suppose you need to onboard a new feature related to tenant isolation in a highly active production system. How would you plan and execute this rollout to minimize risk?
