3 Essential Concepts to Know for AI/ML Interviews

a) Basic Machine Learning Concepts

• Supervised vs Unsupervised Learning

o Supervised: Labeled data (e.g., fraud detection)

o Unsupervised: No labels (e.g., customer segmentation)

• Classification vs Regression

o Classification: Predict categories (spam/not spam)

o Regression: Predict continuous values (sales

forecasting)

• Common Algorithms

o Classification: Logistic Regression, Decision Trees, Random Forest, SVM

o Regression: Linear Regression, Ridge/Lasso

o Clustering: K-Means, Hierarchical

o Recommendation Systems: Collaborative Filtering, Content-based Filtering

b) Model Evaluation Metrics

c) Feature Engineering Basics

• Understanding categorical vs numerical features

• Normalization, encoding, missing value handling

• Feature selection techniques (like PCA)

d) Model Interpretability

• SHAP (SHapley Additive exPlanations)

• LIME (Local Interpretable Model-agnostic Explanations)

• Importance for non-technical stakeholders: "Why did the model predict this?"

e) AI Ethics and Bias

• Data bias, algorithmic bias

• Regulatory compliance (GDPR, CCPA)

• Fairness and transparency

8 Real-World Example for Storytelling

Example Story (Interview Ready):

"In a recent project, I worked on reducing customer churn for a

telecom client I collaborated with data scientists to identify key predictors like usage patterns and service complaints I defined business metrics like churn rate reduction and ensured the model outcomes were explainable using SHAP values I also led

workshops to translate technical results into actionable business strategies, ensuring leadership buy-in."

9 Tips for Interview Preparation

Focus on business value of ML solutions, not model

intricacies

Prepare real examples where you handled AI/ML projects

Brush up on basic ML concepts — enough to discuss

comfortably

Practice explaining technical terms in layman’s language

🎯 Mock Interview Q&A for AI/ML Business Analyst

1 Question: How would you frame a business problem for an AI/ML solution?

Answer:

First, I would work with stakeholders to clearly define the business objective — for instance, "reduce customer churn by 10%." Next, I would explore if we have the right data to predict churn — customer usage patterns, support calls, complaints, etc I would then

collaborate with data scientists to frame it as a supervised learning classification problem: Predict whether a customer is likely to churn

or not I ensure we align on success metrics like Precision and

Recall to evaluate the model, especially if churn events are rare

2 Question: Can you explain the difference between Precision and Recall in simple terms?

Answer:

Sure Precision is about how many of the customers we predicted

would churn actually did churn — it measures correctness Recall is

about how many of the customers who actually churned we were

able to identify — it measures completeness If you think of finding fraud, high precision means few false alarms; high recall means

Trang 10

catching most fraud cases Depending on the business need, like minimizing false negatives in fraud, we might prioritize recall

3 Question: How would you explain model interpretability to non-technical stakeholders?

Answer:

I would explain that while the model gives predictions, we also need

to understand why it makes those predictions For example, if a

customer is likely to churn, interpretability tools like SHAP can show that high complaint frequency and low engagement were major

contributors This helps build trust and enables stakeholders to act

— say, by offering proactive retention measures

4 Question: How do you ensure an AI/ML model is fair and

unbiased?

Answer:

First, during requirement gathering, I discuss fairness goals with stakeholders — for example, ensuring loan approvals are not biased against a particular group I work with data scientists to check if sensitive attributes like gender or race influence outcomes unfairly Techniques like disparate impact analysis and fairness metrics

(e.g., demographic parity) can be applied It's important to

document these checks and ensure transparency

Trang 11

5 Question: Describe a time when data availability or quality impacted your AI/ML project

Answer:

In a customer segmentation project, we found that over 30% of the transaction data was missing or inconsistent Instead of proceeding blindly, I organized a data profiling exercise with the data team to assess the gaps We prioritized high-impact features and used

domain expertise to fill some gaps while discarding unreliable

attributes This collaboration helped ensure the final model was built on clean, representative data

6 Question: What is CRISP-DM and how do you use it in AI/ML projects?

Answer:

CRISP-DM stands for Cross Industry Standard Process for Data Mining It's a structured approach:

• Business Understanding: Define goals and success criteria

• Data Understanding: Gather and explore data

• Data Preparation: Clean and transform data

• Modeling: Build models

• Evaluation: Test if models meet business objectives

• Deployment: Integrate into the business process

Trang 12

As a BA, I am heavily involved in the first two stages to ensure the project aligns with business goals, and in the evaluation stage to validate that outcomes solve the business problem

7 Question: If the AI model predicts incorrectly, how would you explain it to stakeholders?

Answer:

I would explain that no model is 100% accurate — there’s always a trade-off between precision and recall I'd use confusion matrices

to show the different kinds of errors: false positives and false

negatives For instance, if a model incorrectly predicts that a loyal customer will churn, it might be due to sudden changes in behavior that resemble churners Understanding these edge cases helps stakeholders refine intervention strategies

8 Question: What should a Business Analyst focus on when prioritizing AI/ML use cases?

Answer:

Focus on business impact and data availability I look at use cases

where:

• There's a clear ROI (e.g., improving lead conversion rates)

• Historical data is available and good enough for modeling

Trang 13

• The problem is repetitive and large-scale — ideal for

10 Question: What risks would you consider in deploying an AI/ML model?

Answer:

• Bias: Risk of unfair treatment if the training data is biased

• Explainability: Risk if stakeholders can't trust model outputs

• Data Privacy: Compliance with GDPR/CCPA

• Model Drift: Over time, data patterns can change, leading to

decreased accuracy

Trang 14

I work closely with teams to identify, monitor, and mitigate these risks before and after deployment

📚 Quick Role Play Exercise

Scenario: The CEO is skeptical about using AI for customer

support automation

You: How would you explain the value and limitations of an AI

chatbot to the CEO in non-technical terms?

🎭 Role Play Scenario

Stakeholder: CEO — skeptical about using AI for customer

Trang 15

1 Start with Business Value

"First, think of the AI chatbot as an additional support agent available 24/7 It can instantly answer common customer

queries like order status, refunds, or password resets — freeing

up human agents to focus on complex issues This can lead to faster response times, improved customer satisfaction, and cost savings on scaling human support teams."

2 Acknowledge Limitations

"That said, AI chatbots are not magic They excel at handling repetitive, rule-based questions but may struggle with complex, nuanced problems where empathy or critical thinking is

required That's why we recommend a hybrid approach — the chatbot handles first-level queries, and escalates to human agents when needed."

3 Highlight Risk Mitigation

"We will ensure that the chatbot is trained on real customer interactions, continuously monitored, and regularly updated to avoid incorrect or unhelpful responses Also, customers will always have an option to 'talk to a human' if the chatbot cannot resolve their issue."

Trang 16

4 Use a Real-World Example

"Many companies like Amazon and banks have successfully used AI chatbots to handle high volumes of support queries efficiently — not to replace humans, but to enhance customer service operations."

5 Conclude with Business Impact

"By adopting this solution, we can expect improved response times, reduced operational costs, and a better customer

experience — while maintaining human oversight where it

matters most It's about augmenting our team, not replacing it."

🧠 Summary for CEO

• AI chatbot handles repetitive queries 24/7

• Human agents focus on complex, sensitive cases

💡 Tip for Delivery

• Speak calmly and confidently

Trang 17

• Use simple analogies (e.g., "additional support agent")

• Be honest about limitations but show how you’ll manage

them

• Focus on business impact — not technology

🎭 Role Play Scenario

CEO: "What if customers get frustrated talking to a bot?"

You: Business Analyst addressing the concern confidently

✅ Model Answer

"That’s a very valid concern Frustration can happen if the

chatbot isn't designed thoughtfully Let me explain how we plan

to prevent that."

1 Acknowledge the Risk

"You're right — poorly designed bots can frustrate users Our goal is not to make customers 'talk to a bot' endlessly but to use

the chatbot as a quick, efficient first responder."

Trang 18

2 Explain Design Safeguards

"We ensure the chatbot is trained to recognize when it's

struggling — if a customer’s query is complex or the bot detects dissatisfaction (like repeated 'no' or 'not helpful' responses), it

will seamlessly escalate to a human agent This keeps the

customer journey smooth and prevents dead-ends."

3 Highlight Customer Control

"Importantly, we’ll design the chatbot to always offer customers

the choice — they can directly request a human agent at any

time Empowering customers with that option reduces

frustration significantly."

4 Point to User Experience Best Practices

"We’ll keep interactions short, clear, and goal-oriented Instead

of open-ended conversations, the chatbot will offer quick,

action-based menus — 'Track my order', 'Request refund', etc —

so customers feel guided, not trapped."

5 Back it Up with Data or Examples

"In fact, companies that implement escalation policies see up to 30% higher customer satisfaction with chatbots because

Trang 19

customers appreciate the speed but know help is available if needed."

🧠 Summary for CEO

Chatbot will auto-escalate to humans when needed

Customers will have a choice to talk to a human anytime

• Simple, goal-oriented conversation design

frustration

💡 Delivery Tip

• Stay calm — show you acknowledge concerns, but have a plan

• Use phrases like “customer control” and “seamless

escalation” — these are reassuring

• End confidently with customer satisfaction as the focus

Trang 20

🎭 Role Play Scenario

CEO: "How will we measure if the chatbot is actually improving customer service?"

You: Business Analyst explaining the success measurement framework

✅ Model Answer

"That's a critical question — because success isn't just about deploying the chatbot; it’s about demonstrating measurable improvements Let me walk you through how we’ll measure this."

1 Start with Clear KPIs

"We’ll define Key Performance Indicators (KPIs) aligned with business and customer experience goals Some of the core

metrics we'll track include:"

• First Response Time (FRT): How quickly customers get their

first response — a major driver of satisfaction

• Resolution Rate: Percentage of customer queries resolved by

the chatbot without human intervention

Trang 21

• Customer Satisfaction (CSAT) Score: Post-chat surveys

asking customers to rate their experience

• Containment Rate: How many interactions are successfully

handled without escalation to a human agent

• Average Handling Time (AHT): Reduction in time taken per

customer issue

2 Explain Baseline Comparison

"We’ll set a baseline by measuring these metrics with our

current human-only support system Then, after chatbot

deployment, we’ll compare to see if there’s an improvement — for instance, faster response times, higher resolution rates, and better CSAT scores."

3 Highlight Business Impact Metrics

"Beyond customer experience, we’ll also monitor operational metrics like:"

• Cost per Contact: Lowering the average cost to handle a

customer query

• Agent Productivity: Human agents handling fewer repetitive

queries and focusing on higher-value tasks
