CNN
CNN (Convolutional Neural Network) is a popular type of artificial intelligence system that's especially good at understanding and analyzing images and videos. Think of it like a digital brain that can learn to recognize patterns in pictures, similar to how humans can identify objects, faces, or text in images. When you see this term in resumes, it usually means the candidate has experience with advanced image processing or computer vision projects. It's one of the fundamental building blocks used in many modern AI applications, from facial recognition to medical image analysis. Other similar terms you might see include "Deep Learning," "Neural Networks," or "Computer Vision."
Examples in Resumes
Developed CNN models for automated quality control in manufacturing
Implemented Convolutional Neural Network architecture for facial recognition system
Created CNN based solution for medical image analysis

Example Interview Questions
Senior Level Questions
Q: Can you explain how you would approach solving a complex image recognition problem using CNNs?
Expected Answer: A strong candidate should explain in simple terms their process: starting with data collection, choosing the right model architecture, training strategy, and how they would measure success. They should mention practical considerations like computing resources and potential challenges.
Q: How would you optimize a CNN model that's performing poorly?
Expected Answer: Look for answers that discuss practical approaches like adjusting the model size, improving training data quality, addressing overfitting/underfitting, and methods to make the model more efficient while maintaining accuracy.
Mid Level Questions
Q: What are the basic components of a CNN and how do they work together?
Expected Answer: Candidate should be able to explain in simple terms how CNNs process images through layers, similar to how human brains process visual information, without getting too technical.
Q: Can you describe a real-world project where you used CNNs?
Expected Answer: Look for practical experience in implementing CNN solutions, understanding of project requirements, and ability to measure and achieve results.
Junior Level Questions
Q: What is a CNN and what is it commonly used for?
Expected Answer: Should be able to explain that CNNs are AI systems specialized for processing images and videos, and give basic examples like face recognition or object detection.
Q: What tools or frameworks have you used to work with CNNs?
Expected Answer: Should mention common tools like TensorFlow or PyTorch and demonstrate basic understanding of how to use them for simple image processing tasks.
