Cloud Platforms: AWS (SageMaker, EC2), Google Cloud (Vertex AI), Azure ML
MLOps: MLflow, Docker, Kubernetes, CI/CD pipelines
Domain Knowledge: Computer Vision, NLP, Time Series, Recommendation Systems
Building an Impressive Portfolio
Portfolio Project Criteria
Choose projects that showcase:
- Real data: Use actual datasets or create realistic scenarios
- Complete pipeline: From data collection to deployment
- Technical depth: Advanced ML techniques, not just basic models
- Documentation: Clear README, reproducible code, insights
- Business value: Explain how your solution creates value
GitHub Best Practices
- Well-organized repository structure
- Comprehensive README with project description, setup instructions, results
- Reproducible code with requirements.txt
- Jupyter notebooks showing analysis and results
- Performance metrics and visualizations
- Clear commit history showing development process
Technical Interview Preparation
Common Technical Questions
- Explain the difference between supervised and unsupervised learning
- What is the difference between classification and regression?
- How do you handle missing data in datasets?
- What is overfitting and how do you prevent it?
- Explain cross-validation and its importance
- What are common evaluation metrics for classification?
- Explain precision, recall, and F1 score
- What is the difference between L1 and L2 regularization?
- How do you approach feature selection?
- What is a confusion matrix and how do you interpret it?
- Explain the bias-variance tradeoff
- What is the difference between batch and stochastic gradient descent?
- How do you handle imbalanced datasets?
- What are hyperparameters and how do you tune them?
- Explain the curse of dimensionality
System Design Questions
- Design a recommendation system for an e-commerce platform
- Design a fraud detection system for credit card transactions
- Design a ML pipeline for a production environment
- How would you build a real-time anomaly detection system?
- Design a demand forecasting system for retail
Interview Problem-Solving Strategy
For technical problems:
- Clarify requirements – ask questions
- Discuss approach before coding
- Explain your reasoning
- Write clean, modular code
- Test your solution
- Discuss complexity (time, space)
- Suggest improvements
Behavioral Questions
Why do you want this role? Research the company, align with their mission, explain specific interest
Tell me about a challenging project Use STAR method, show problem-solving, learning, collaboration
How do you handle failure? Give specific example, explain what you learned, how you applied it
Describe a time you had to learn something new quickly Show initiative, learning ability, resilience
Common Interview Mistakes
- Not understanding the basics: Make sure you can explain fundamental ML concepts clearly
- Claiming unverified skills: Only list what you can actually do
- Not asking clarifying questions: Shows you don’t think deeply
- Overfitting to memorized solutions: Interviewers want to see thinking, not memorization
- Not discussing tradeoffs: ML involves decisions, explain why you chose certain approaches
- Poor time management: Finish on time, don’t spend 30 minutes on part 1
- No questions for interviewer: Always ask thoughtful questions
Salary Negotiation Tips
- Research salary ranges: Levels.fyi, Glassdoor, Blind
- Don’t disclose previous salary: Set your range first
- Negotiate the total package: Base + bonus + stock + benefits
- Get the offer in writing
- Know your market value: More experience = higher expectations
Conclusion
Landing an AI job requires more than technical knowledge. Your resume must communicate impact, your portfolio must demonstrate depth, and your interviews must show both expertise and communication ability. Start preparing early, practice consistently, and approach each interview as an opportunity to learn and refine your narrative.
