AI Project Manager - Architect - Interview Question and Answer
1. Identifying and prioritizing language model issues, and working with researchers to find a path to resolution.
Q: Can you walk us through your process for identifying and prioritizing issues in a language model?
✅ Sample Answer:
"I start by defining clear evaluation criteria for the model's performance, such as accuracy, bias, coherence, and safety. I use both automated metrics (e.g., perplexity, BLEU scores) and human evaluations to identify areas of concern. Once issues are identified, I prioritize them based on impact—factors like user experience, ethical concerns, and business objectives. After prioritization, I collaborate with researchers to determine the best resolution approach, whether it’s prompt engineering, fine-tuning with additional data, or refining underlying model architectures."
2. Creating novel data collection tasks for taskers to evaluate language models and to collect training data for fine-tuning.
Q: How do you design an effective data collection task for fine-tuning a language model?
✅ Sample Answer:
"Designing an effective data collection task starts with defining the model’s weaknesses and the type of data needed to improve performance. I ensure the task is clear, reproducible, and aligned with the end goal. For example, if a model struggles with sarcasm detection, I might design a crowdsourcing task where annotators label sentences as literal or sarcastic. I also implement quality control mechanisms such as gold-standard examples and inter-annotator agreement to ensure data reliability."
3. Creating language model prototypes to prove out new feature directions and scope projects.
Q: Can you describe a time when you built a prototype to test a new feature in a language model?
✅ Sample Answer:
"In a previous project, I was exploring the use of retrieval-augmented generation (RAG) for improving factual accuracy. I built a prototype integrating an external knowledge base with a transformer model, allowing it to reference up-to-date facts before generating responses. I conducted qualitative testing with human reviewers and quantitative evaluations using knowledge benchmarks. The prototype demonstrated significant improvement in factual accuracy, leading to further development and eventual deployment."
4. Engineering prompts to teach language models how to behave across a wide range of scenarios.
Q: How do you approach prompt engineering to optimize model behavior?
✅ Sample Answer:
"I use an iterative approach to prompt engineering, beginning with clear instructions and constraints. I experiment with different phrasing, formatting, and few-shot examples to guide the model’s response. For instance, if I want a model to generate unbiased summaries, I may use a structured prompt like: ‘Summarize the following article in a neutral tone without adding personal opinions.’ I also test prompts across diverse scenarios to ensure consistency and refine them based on outputs and evaluation metrics."
5. Working closely with researchers and engineers to define and manage engineering and research projects.
Q: How do you ensure effective collaboration between research and engineering teams?
✅ Sample Answer:
"I bridge the gap between research and engineering by establishing clear project goals and expectations. I define measurable success criteria and create a shared roadmap with well-defined milestones. Regular check-ins, documentation, and knowledge-sharing sessions help keep everyone aligned. For example, in a recent project, I worked with researchers to fine-tune a model while ensuring engineers could deploy it efficiently in production, balancing performance improvements with deployment feasibility."
6. Deploying and tracking AB model experiments in production.
Q: What metrics do you track when running an A/B test on a language model?
✅ Sample Answer:
"I track key performance indicators (KPIs) based on the model’s intended purpose. These may include response accuracy, user engagement, completion rates, and latency. I also monitor user feedback and error rates. For instance, if testing a new chatbot response model, I might compare conversation retention, correctness scores, and satisfaction ratings between the control and test groups. Statistical significance testing ensures valid conclusions before rolling out changes.
A/B testing, also known as split testing, is a method that compares two or more versions of a webpage, app, or email to determine which performs better based on specific metrics like conversions or engagement
A/B testing allows for data-driven decision-making, enabling businesses to optimize their digital assets and improve user experience. "
Bonus Question
Q: How do you ensure language models remain fair, unbiased, and aligned with ethical AI principles?
✅ Sample Answer:
"I use a combination of bias detection tools, diverse datasets, and human evaluation to monitor fairness. I also implement reinforcement learning from human feedback (RLHF) to align the model with ethical guidelines. When biases are detected, I work with researchers to mitigate them through dataset augmentation, prompt modifications, or model fine-tuning. Transparency is key—I document limitations and ensure user-facing models have disclaimers where necessary."
