I was asked to discuss some LLM projects I had worked on, exploring the technical aspects and including one or two theoretical questions.
Machine Learning Interviews
Machine Learning Interview Questions
"To get a job in machine learning, you must have the programming and mathematical knowledge to create artificial intelligence that is capable of learning new tasks without being explicitly coded. In an interview you may be asked about your experience with pertinent coding languages such as Java and C++ as well as with writing algorithms. The interview will be comprised mainly of technical questions that test your knowledge of the fundamental concepts of machine learning such as data mining and signal processing."

How would I approach one case
A large part of the interview focused on my PhD thesis. After I explained my research at the beginning, the interviewers asked in-depth questions to assess how well I understood my own work. Later, they asked machine-learning–related questions relevant to the role, including hypothetical scenarios about how I would approach and analyze a given type of data etc.
Some fundamental machine learning questions and then a deep dive into RAG system components.
CNN mechanism, filters, pooling layers, Transformer mechanism, positional encoding
1: ¿Cómo diseñarías una arquitectura de MLOps completa para gestionar modelos de machine learning en producción, garantizando escalabilidad, observabilidad y reproducibilidad? R: Expliqué un enfoque basado en Kubernetes, CI/CD, pipelines de MLOps, monitoreo con Prometheus/Grafana, gestión de artefactos y modelos en MLflow, y despliegues controlados con infraestructura como código. P2: ¿Cómo gestionarías la integración de flujos de datos de diferentes equipos dentro de un entorno corporativo de gran escala? R: Describí estrategias de integración mediante API Gateways, control de versiones de datos, almacenamiento distribuido y monitoreo de la calidad del flujo de datos. P3: ¿Cómo garantizarías la seguridad, cumplimiento y eficiencia en entornos híbridos de entrenamiento y producción de modelos? R: Comenté el uso de IAM, redes privadas virtuales, control de acceso granular, auditorías automáticas y prácticas de DevSecOps. P4 (Presentación técnica): P1: ¿Cómo diseñarías una arquitectura de MLOps completa para gestionar modelos de machine learning en producción, garantizando escalabilidad, observabilidad y reproducibilidad? P2: ¿Cómo integrarías flujos de datos de diferentes equipos dentro de un entorno corporativo de gran escala? P3: ¿Qué medidas aplicarías para garantizar seguridad y cumplimiento en entornos híbridos (on-premise y cloud)? P4: Durante la presentación técnica, se pidió exponer un caso real de arquitectura aplicada a entornos de IA, detallando decisiones técnicas, automatización y gestión operativa.
1. Explain the E2E architecture of a multi-agent system that you have built? 2. Explain how BERT works? 3. How do you evaluate RAG system?
Q: How do you evaluate the performance a classifier?
Q: Tell me about yourself. Q: Why did you quit your last job? Q: What's your salary expectation? (Even they company didn't consider to give me an offer)
