For international students hoping to land a job in AI in North America, starting from scratch requires a combination of fundamental knowledge and hands-on skills. The first step is to understand the core areas of AI basics. The North American job market is divided into roles like machine learning engineers, data scientists, computer vision engineers, and NLP engineers, each with a unique skill set and job outlook.
Mathematics is a critical part of AI learning but you don’t need to dive into complex theories immediately. Focus on key concepts in linear algebra, such as matrix operations and eigenvalue decomposition, in statistics, understand Bayes’ Theorem and distributions, and in calculus, focus on the concept of gradients. A practical approach is to combine learning Python with math. For example, you can use NumPy to practice matrix operations, which helps you understand math and programming simultaneously. A student I know successfully improved their math skills in just three months using this method.
Programming skills are a must, with Python being the primary language. Start with basic syntax and focus on libraries like NumPy and Pandas for data manipulation, then move on to Scikit-learn for machine learning. There are lots of valuable learning resources on GitHub, such as the "100-Days-Of-ML-Code" project, which is great for self-study. It’s also important to develop good coding habits, as North American employers look for clean, readable, and modular code, especially in interviews.
The journey of learning machine learning should be gradual. Begin with supervised learning techniques, like linear regression and decision trees, then move to unsupervised learning such as clustering and dimensionality reduction. For deep learning, start with simple models like fully connected networks. It’s helpful to apply what you learn by working on projects. Platforms like Kaggle provide many beginner-friendly challenges and datasets. One of the students I mentored got their first internship by completing a beginner-level project like Titanic survival prediction.
In North America, practical experience is highly valued in the AI job market. There are three main ways to gain this experience: contributing to university research, engaging in open-source projects, and securing internships. Even roles like teaching assistant or participation in hackathons can enhance your resume. A student from New York University, for example, was invited to interview at Facebook after sharing their personal algorithm library on GitHub.
Job preparation should also consider the North American interview process. Technical interviews often focus on algorithm problems (usually medium difficulty on platforms like LeetCode) and machine learning theory, while behavioral interviews focus on your project experience and problem-solving abilities. It’s a good idea to form a study group for mock interviews, focusing on whiteboard coding and case study analysis. One tip is to frame your past projects using the STAR method, which is very effective during behavioral interviews.
Finally, the AI job market in North America is competitive. It’s recommended to plan for 18-24 months of study, with a weekly learning schedule of 20 hours, balancing coursework, hands-on projects, and job preparation. The key to success isn’t how quickly you learn, but how well you learn. With patience and persistence, you can find a place in the North American AI field.
