AI Interview Questions You Need to Know | iCertGlobal

Artificial Intelligence (AI) continues to form a significant part of the way businesses unction in present-day society. From health care to finance, there are many businesses searching for AI professionals to help find solutions to challenges and improve processes. The World Economic Forum states that by 2030 AI and automation could potentially create a total of 170 million new positions. However, there are still not enough qualified workers to accept the open roles that are available.

A. Common AI Interview Questions and Sample Answers

Whether you are preparing to launch a career in Artificial Intelligence  or you are already working in the field and are seeking a new opportunity- the future looks promising. The only caveat is that there are a lot of other people seeking a career in this field! To stand out as a viable job candidate, you will want to secure certifications in AI and be prepared to answer key AI interview questions.

1.What are the different types of AI?

 The four types of Artificial Intelligence are Reactive Machines, Limited Memory, Theory of Mind, and Self-aware AI. These types represent the timeline of AI becoming smarter. First, there are simple reactive machines that only react to things. Next, we have an AI built with limited memory to observe and learn from its environment and improve its behaviors. Third, is an Artificial Intelligence that develops and applies human cognitive skill sets when thinking for itself. Finally, self-aware AI is an AI that can be able to consider its own state, potentially become a sentient and autonomous being capable of human triggers and human activities.

2. How does machine learning (ML) differ from programming?

With programming, you are writing code that tells a computer what to do and how to make decisions. With machine learning, the computer learns from data by recognizing patterns, and makes decisions itself, without human assistance.

3. What is a convolutional neural network (CNN)?

A Convolutional Neural Network (CNN) is a type of AI that can read images. Usually Artificial Intelligence, sees a whole image at once. CNNs take the image piece by piece, figure out how to interpret its characteristics, and ultimately, figure out what is in the image.

B. Artificial Intelligence Interview Questions for Freshers

1. What is Artificial Intelligence?

Artificial Intelligence (AI) refers to programming machines to be able to think and learn like humans. Artificial Intelligence aims to design machines that can perform specific tasks, where human thinking is required, such as reading images, interpreting speech, making decisions, and translating from one language to another

2. Can you explain the difference between AI, Machine Learning, and Deep Learning?

• AI is the broad field of creating smart machines.
• Machine Learning (ML) is a part of Artificial Intelligence that helps machines learn and improve from experience.
• Deep Learning is a part of ML that uses special networks (called neural networks) with many layers to help machines learn from lots of data. It's good for tasks like recognizing images or understanding speech.

3. What is a Neural Network?
A Neural Network is a system of algorithms designed to work like the human brain. It helps machines find patterns in data and make decisions. It has layers of "neurons" that learn different features from the data.

C. Artificial Intelligence Interview Questions for Experienced

1. What is Q-Learning?
Q-Learning is a way for a machine (called an agent) to learn the best actions to take in different situations to get the most rewards. The agent uses a table (called the Q-function) to keep track of the expected rewards for each action it can take. The agent updates the table using a formula called the Bellman equation, which helps it make smarter decisions as it learns.

2. Which Assessment is Used to Test the Intelligence of a Machine? Explain It.
The Turing Test is used to check if a machine can think like a human. In this test, a person talks to both a human and a machine, and the person doesn't know which is which. If the person can’t tell which is the machine, the machine is said to be intelligent.

3. What is Reinforcement Learning, and How Does It Work?
Reinforcement Learning (RL) is a type of machine learning where an agent learns by interacting with its environment. It receives rewards or penalties based on its actions and tries to learn the best actions to get the most rewards over time.

D. Artificial Intelligence Scenario-Based Questions

Scenario 1: Predictive Maintenance in Manufacturing
Question: A manufacturing company wants to minimize downtime and reduce maintenance costs on their machinery. How can AI help achieve these goals?

Answer: Artificial Intelligence can be used for predictive maintenance, where it analyzes data from machine sensors (like temperature, vibration, and sound) to predict when a machine might fail. By learning from past data, Artificial Intelligence can spot patterns that show when a machine is about to break down, allowing the company to fix it before it causes a problem. This helps reduce unexpected breakdowns and saves on maintenance costs.

Scenario 2: Personalizd E-commerce Recommendations
Question: An e-commerce platform wants to increase sales by offering personalized product recommendations to its users. How can Artificial Intelligence be used to enhance the shopping experience?

Answer: Artificial Intelligence can create a personalized shopping experience by analyzing the user's past behavior, like browsing and purchasing history. Using machine learning, the system can predict which products the user might be interested in and recommend those items. This helps increase sales and customer satisfaction by showing users products they are more likely to buy.

Scenario 3: Enhancing Cybersecurity with AI
Question: A financial institution faces sophisticated cyber threats that are changing quickly. How can Artificial Intelligence help strengthen their cybersecurity measures?

Answer: AI can help detect and prevent cyberattacks by monitoring network traffic and user behavior in real-time. It learns from past threats and can quickly identify unusual activities, allowing the institution to react faster to potential threats. AI can also automatically handle certain security tasks, making cybersecurity more efficient and less prone to human error.

E. AI Interview Questions on Advanced Topics

1. What is the difference between supervised, unsupervised, and reinforcement learning?

• Supervised learning: The model learns from labeled data, meaning the correct answers are already provided.
• Unsupervised learning: The model learns from data without labels, finding patterns on its own.
• Reinforcement learning: The model learns by interacting with its environment, receiving rewards or penalties based on its actions to improve over time.

2. What is transfer learning?
Transfer learning is when a model built for one task, like image recognition, is used for another related task, such as object detection. This saves time and resources because the model has already learned useful information from the first task.

3. What is Explainable AI (XAI)?
Explainable AI (XAI) is a field that aims to make machine learning models more understandable. It helps people see why a model made a specific decision, which is important in areas like healthcare and finance, where decisions need to be explained.

F. AI Interview Questions and Answers on Generative AI

1. What is Generative AI?
Generative Artificial Intelligence creates new content like images, text, or music by learning patterns from data. Unlike regular AI, which only predicts or classifies, generative AI can make completely new, original data.

2. How do Generative Adversarial Networks (GANs) work?
GANs have two models:

• Generator: Makes fake data.
• Discriminator: Tries to tell if the data is real or fake. They work together: the generator keeps improving to fool the discriminator, and the discriminator gets better at spotting fake data.

3. What are Variational Autoencoders (VAEs)?
VAEs are a type of generative model that learns to simplify data (in a latent space) and then recreates it. This helps VAEs generate new data similar to the original, based on patterns they’ve learned.
