JPMorgan Chase DevOps / SRE Interview Questions

1.Describe a time when a teammate was struggling with their workload or technical challenges. How did you identify this was happening and what did you do to help them?

2.Describe a time when you had to implement a change or deploy something with significant risk. How did you minimize that risk and what safeguards did you put in place?

3.Tell me about a time you had to choose between making your life easier as an engineer and doing what was best for the client or business. What was the situation and how did you decide?

4.Give me an example of when you automated or optimized something that saved significant time for your internal customers or other engineering teams. What did you build and how did you measure the impact?

5.Walk me through the last production incident where you were the primary responder. What broke, how did you diagnose it, and what was your communication strategy during the outage?

6.Tell me about a time you had to give difficult feedback to a peer or someone you worked closely with. What was the feedback about, and how did you approach delivering it?

7.You need to deploy a new microservice that handles payment processing to our Kubernetes cluster. Walk me through your deployment strategy, considering we process $10 trillion daily.

8.Write a Python script that monitors Kafka topic lag across our payment processing clusters and automatically scales consumer groups when lag exceeds thresholds.

9.Our Chase Mobile app is experiencing 500ms API response times during peak trading hours, affecting 80 million customers. How would you investigate and resolve this?

10.Design a monitoring and alerting strategy for our Onyx blockchain platform that handles enterprise JPM Coin transactions. What key metrics and SLIs would you track?

11.You're migrating a legacy Oracle database that handles derivatives pricing to AWS. The current system has 20+ year old stored procedures critical to J.P. Morgan Markets. How do you approach this migration?

12.Our internal AI LLM Suite is experiencing high GPU utilization and 30-second response times for 200k employees. How would you optimize the infrastructure to improve performance?

13.We need to implement zero-downtime deployments for our J.P. Morgan Markets trading platform that handles millions of trades per second. Walk me through your blue-green deployment strategy.

14.Our Onyx blockchain platform needs to handle enterprise JPM Coin transactions with guaranteed settlement finality. Design the consensus and validation layer for this permissioned network.

15.Our internal LLM Suite needs to scale from 200k employees to potentially all bank employees globally while maintaining sub-5 second response times. How would you design the infrastructure to support this growth?

16.Design a real-time fraud detection pipeline for Chase Mobile that can process 80 million customer transactions with sub-100ms latency while maintaining our current fraud detection accuracy. What's your architecture?

17.Design a disaster recovery system for JPMorgan Payments that can handle failover across AWS regions while maintaining our daily $10 trillion processing volume. What's your approach to ensuring zero data loss during region outages?

18.Design a configuration management system for our Kubernetes clusters that handles secrets rotation across 1000+ microservices while maintaining compliance audit trails. How do you ensure secure and traceable config changes?

19.Tell me about a time when you had to onboard a new team member during a critical project or incident. How did you balance their learning needs with delivery pressure?

20.Give me an example of when you had to coordinate with multiple engineering teams to deliver something that none of you could accomplish alone. What was your role in making that collaboration successful?

21.Tell me about a time you had to convince engineering leadership to invest in infrastructure improvements that wouldn't deliver immediate business value. How did you build the case and what was the outcome?

22.Walk me through a time when you identified a security or compliance gap in your systems. How did you prioritize addressing it against other competing work?

23.Describe a situation where you disagreed with your manager's technical approach on a critical project. How did you handle the disagreement?

24.Describe a time when you identified that your team's current approach wouldn't scale to meet future demands. How did you lead the transition to a better solution?

25.Chase Mobile processes 80 million customer transactions daily. If our fraud detection system has a 1% false positive rate, estimate the annual cost of these false positives and walk me through your assumptions.

26.Estimate the annual cost impact if our AWS data transfer charges increased by 25% due to our cloud migration progress. Factor in JPMorgan Chase's current 70% cloud data residency.

27.Our JPMorgan Payments platform shows a 5% decrease in daily transaction volume over the past week with no deployments or incidents. How would you investigate this drop?

28.Estimate how much additional infrastructure cost JPMorgan Chase would incur annually if we reduced API response times across all services by 50ms to improve client experience.

29.Our Onyx blockchain platform needs to maintain 99.99% uptime for JPM Coin settlements while handling regulatory audits. How would you design monitoring to detect both technical issues and compliance violations?

30.Our internal LLM Suite shows uneven usage across different business lines despite being available to all 200k employees. Design an investigation to understand adoption barriers and estimate the revenue impact of low adoption in Markets trading.
