Learn techniques for image classification, object detection, image segmentation, image generation and more. Study convolutional neural networks (CNNs), recurrent neural networks (RNNs), long short-term memory networks (LSTMs) and other architectures used for computer vision.

Natural Language Processing

Understand how machine learning enables computers to process, parse and generate human language. Study techniques like tokenization, stemming, lemmatization, named entity recognition, part-of-speech tagging, sentiment analysis and more. Learn about transformer architectures used in large language models.

Probabilities, Statistics and Calculus

Refresh key mathematical concepts frequently used in AI algorithms including derivatives, integrals, linear algebra, probabilities, hypothesis testing, regression analysis, and multivariate calculus. Connect the math to how it enables machine learning.

AI Programming

Practice core programming skills needed for AI applications. Become fluent in languages like Python and R commonly used for machine learning. Gain experience with important AI libraries like TensorFlow, Keras and PyTorch. Implement algorithms both from scratch and using established libraries.

AI Ethics

Learn principles of ethical AI development and deployment. Study techniques for bias detection, explainability, accountability and algorithm auditing. Understand ethical implications around AI and data privacy.

Aim to dedicate around 300 hours to immerse yourself in fundamental AI concepts. Take online courses, read textbooks and research papers, complete projects, and implement algorithms hands-on. The deeper your grasp of core AI, the better you can discuss details and make connections in interviews.

Step 2: Thoroughly Research the Company and Role

Once you have identified an AI role to apply for, conduct extensive research on the company, their industry, products, and culture. Dedicate 10+ hours to learning as much as possible.

  • Study the company website, press releases, leadership bios, blogs, news mentions, job postings and other materials.
  • Download and explore any software products and mobile apps they offer.
  • Follow the company and employees on social media to gain real-time insights.
  • Search media and industry reports for third-party analysis on the company, competitors, trends, and innovations.
  • Identify current employees on LinkedIn with similar roles to understand common backgrounds and required skills.
  • Find the hiring manager and interviewers on LinkedIn to customize your interactions for their priorities.

As you conduct research, take notes on:

  • How the company applies AI across its products and services
  • The AI technologies and techniques commonly used
  • Domain-specific terms and acronyms
  • Major initiatives, competitors, challenges or controversies
  • Company culture and mission
  • Biographies and interests of the interviewers

This research equips you to ask strategic questions and hold intelligent conversations that demonstrate your interest, knowledge, and alignment with the company’s needs and values.

Step 3: Quantify and Highlight Relevant Experience

Carefully review the job description, noting required and preferred qualifications. Reflect on your projects, education, skills and experience that directly relate. Quantify past achievements and contributions using metrics like:

  • AI models built, detailing the data sources, algorithms, frameworks used and accuracy achieved
  • Improvements in key performance indicators driven by AI implementations
  • Amount of data evaluated, processed or labeled
  • AI products conceptualized and brought to market
  • Technical documents authored on AI topics
  • Presentations given on AI projects
  • Examples of collaborating across teams to solve problems using AI

Update your resume and LinkedIn profile to strategically highlight relevant experience using terminology from the job description. Prepare code samples, writing samples, or example projects that demonstrate you have the required abilities. Quantifying your contributions makes them more tangible and memorable.

Step 4: Practice Responding to Common Interview Questions

Conduct extensive research on the types of technical and behavioral interview questions commonly asked for similar roles. Compile a list of 20-30 likely questions and practice responding out loud to each one.

For technical questions, focus your responses on clearly explaining your thinking process:

  • How would you evaluate the quality of data used to train an image classification model?
  • What techniques would you use to tune hyperparameters of a deep neural network?
  • What are the advantages and disadvantages of various evaluation metrics for NLP models?

Structure responses using frameworks like:

  • Describe the key considerations
  • Explain potential approaches
  • Analyze the tradeoffs of each approach
  • Recommend an optimal approach based on the context

Time yourself so answers are concise and comprehensive. Provide examples when possible to support your responses.

For behavioral questions, apply the STAR method:

  • Situation – Briefly summarize the context
  • Task – Describe what needed to be achieved
  • Action – Explain the actions you personally took
  • Result – Share the outcomes and impact achieved

Practice repeatedly until you are comfortable responding confidently to likely interview questions. Refine answers to be clear and get to the point quickly.

Step 5: Complete Mock Interviews

Setting up mock AI interviews is one of the most effective preparation techniques. Treat each practice interview like the real deal:
