In the interview, they asked questions related to the basics of machine learning, deep learning, computer vision, and natural language processing. They likely focused on understanding your knowledge of algorithms, models, and techniques used in these fields. Questions could have included topics like supervised and unsupervised learning, neural networks, convolutional neural networks (CNNs) for image processing, object detection, and models like transformers for natural language processing (NLP). They may have also tested your ability to explain key concepts like loss functions, activation functions, and performance evaluation metrics.
