Osama presented a new architecture for log ingestion with ServiceNow. He and his team developed it over the past year. He demonstrated strong technical depth and project leadership, moving seamlessly between high-level architecture discussions and detailed deep dives into his focus areas.

Areas of strength included:

• Project foundation: Clearly articulate the project background, team structure and system architecture. Provide sufficient context so interviewers understand the scope and complexity of the work. 
• Challenge and Trade-offs: Token deactivation is a good example for short term and long term trade-offs, also demonstrated candidate’s detail oriented spirit

Areas for improvement:

• Visual aids: Prepare a diagram illustrating the high-level architecture and key components of your project. This will help interviewers quickly grasp the system design and understand your specific contributions.
• Impact and metrics: Be ready to discuss quantifiable impacts from multiple angles—business outcomes (e.g., adoption rate, # of adoptions), system performance improvements (e.g., latency reduction, throughput gains), and operational efficiencies (e.g., reduced incidents, customer operational cost reduction).
• Challenges and trade-offs: Prepare an additional example that demonstrates greater technical depth. In particular, develop a clearer explanation of the Kafka partitioning strategy and how you addressed the log ordering problem, including the trade-offs you considered and why you chose your approach.

Overall, Osama shows strong potential and with focused practice on the areas mentioned above, should be well-prepared for upcoming interviews.
