They ask me about how to design a metric to measure the time to which the food is prepared vs. the rider is arrived at the shop.

Machine Learning Theory Interview (By Hiring Manager) 1. Interviewer started asking about my thesis and asked questions about IMU sensor, Odometry 2. Classification metrics (Precision, Recall, curves - what is measured along X, Y and how is area calculated, how you conclude about best threshold) 3. Decision Trees and Random forest regularization techniques 4. Advantages of LLM over LSTM 5. Explain LLM architecture and every layer functionalities 6. Scenario-based question: How would you ensure a particular class is distinguished correctly during training and achieves zero errors? (By assigning a higher weight to that class during training.) 7. Explain about Adaboost and how you can modify according to your dataset 8. Scenario based: If the Product Manager provides a new requirement, how would you approach and execute it? 9. Scenario based: Explain a scenario from your prev experience where you had to work with multiple stakeholders 10. Scenario based: You are given a requirement to develop a solution that relies on external AI APIs. However, the Product Manager does not want any sensitive data to be sent outside the system. How would you handle this situation? I would initially use the external APIs but ensure that all sensitive user data is masked or anonymized before sending any requests. This allows rapid prototyping while keeping data privacy intact. In parallel, I would begin working on developing an in-house model capable of handling the required tasks, so that we can eventually migrate away from external APIs entirely. (This was the same approach eventually adopted by the team.)
Top Grading Discussion (By Director - Applied Science) This round involved a deep dive into my projects, my role at Walmart, and my hackathon experiences. The interviewer focused on understanding my overall approach, problem-solving process, and decision-making rationale. I was asked questions such as why I selected particular models, what training strategies were used for fine-tuning, how knowledge distillation was applied, and other aspects that revealed technical depth and reasoning.
Coding question: search for an element in a sorted matrix
deep learning and machine learning related stuff
The coding question covered implementing an ML algorithm in NumPy, and the system design round is focused on a real world problem related to the team's work. Due to the fact that they are concerned about the culture, I discovered that behavioral interviews are also important to them.
- The python coding parts mainly involved working with dictionaries. - The technical parts were on hypothesis testing and experimentation. - The HR part was on standard HR questions like why yelp etc. - No feedback was provided despite having gone to the final interview which was disappointing.
do expect anything/ models on your resume
This is THE best interviewing experience I've ever had! Everyone I talked to was sharply smart but humbly polite. HR was very efficient and helpful. There are some behavior questions but all are closely to the business (e.g., how do you communicate with audiences from different backgrounds). Most rounds have cases, highly relevant to the team's business and models. For coding I personally think it is not too difficult, but they value how you approach the question/communicate/constantly think about how to improve.
Explain Vision transformers and CNN. Overfitting. Linear regression. System design involving multi-modal GenAI models.
