What is Chain-of-thought (CoT) reasoning and how important is it in Agentic AI?
Chain-of-thought reasoning is a technique that AI agents use to break a complex problem into intermediate steps to provide accurate results. It is important because:
Rather than guessing the output, the AI Agent reasons through the tasks, plans the steps, and completes them to improve accuracy.
Completes multi-step tasks that require reasoning and planning.
Easier to debug and interpret results.
When should you implement multiple agents in place of one agent with multiple tools?
Multiple agents should be implemented when the tasks are separable and properly specified. Other reasons include:
Parallel Work: The tasks can be performed independently at the same time.
Security Reasons: Some agents are required to be restricted from accessing tools or databases.
Long Task Chain: A single agent cannot remember the earliest step when it executes a long task chain. So a multiple-agent system would be preferable.
What would you do to debug a multi-agent system that produces wrong output?
Candidates need to describe from their experience how they debugged a system producing wrong output. If they have not done it practically, then explain it through theory. A sample answer would be:
Step 1: Trace the workflow, including the tool use, prompts, and handoffs between agents.
Step 2: Start from the wrong output and trace the workflow backward to see which agents or part of the process shows failure. Isolate that agent or step.
Step 3: Check what recurring failure pattern your failure matches to find the fix.
Step 4: Find the root cause of the problem and apply the solution.
What are the security concerns regarding deploying autonomous agents?
The security risks related to AI Agent deployment are:
Prompt injection: Agents receive malicious inputs in the form of prompts, making them ignore the predefined rules and instructions and leak sensitive information.
Cascading Error: An error in the earlier steps cascades and affects the output of other agents.
Risks Sensitive Data: Due to tool misuse or agents exchanging data autonomously, sensitive information can be leaked.
Over-access: When an AI agent has excessive access to tools and other resources, more than it needs, it can cause security issues.
What is the human-in-the-loop approach and why is it needed?
Human-in-the-loop approach (HITL) refers to the involvement of humans in the AI system's lifecycle. The human supervises the AI workflows, including its operation, decision-making process, and learning, to ensure safety and accuracy.
HITL process is needed because it helps ensure:
The AI system produces accurate output and does not misuse information.
AI agents are not solely responsible for actions; HITL ensures proper accountability for actions.
HITL helps improve fairness in outputs by reducing data bias.
Involvement of humans in the workflow increases the trust of users in the system.
How do you prevent your agent from getting stuck in an infinite planning or execution loop?
To prevent my agents from getting stuck in an infinite planning or execution I follow these steps:
Set a maximum number of interactions or hop counts allowed.
Implement termination functions that help agents terminate the task before hitting the allowed hop counts.
Spot the agents that are showing repetitive behaviors, providing the same responses or output.

FAQs
Are Agentic AI roles more advanced than traditional AI roles?
Yes, Agentic AI roles are more advanced because they don’t just stop at training AI models that complete well-defined tasks. Agentic AI roles require candidates to build multi-agent systems that work autonomously. Candidates need to ensure security and design safe and reliable systems that can manage entire workflows, plan tasks, reason, use tools, and make decisions, all on their own.
How to prepare for Agentic AI Interviews?
Start with strengthening your basics; learn how AI agents work, practice the frameworks, and address security concerns. Practice the Agentic AI interview questions, take mock interviews, and identify your areas of weakness. Read newsletters and reports to stay updated.
Is Agentic AI the future?
Yes, Agentic AI is the future of artificial intelligence, shifting from completing tasks to managing entire workflows. Most companies plan to deploy AI agents in the coming years, and the demand for Agentic AI is increasing.
Although Agentic AI promises several benefits, there are still challenges such as agents getting stuck in infinite loops and cascading errors, sensitive data leakage through tool misuse, lack of accountability, and over-permissioning.
