First-hand accounts from people who interviewed at Fusemachines.
Fellowship
The interview was virtual. I had to wait a bit before it started. There was a booking system where I had to reserve a time slot for the interview. Be aware, you can't book more than one slot, or they'll reject your application.
No confirmed questions were included in this interview report.
ML Engineer
The process started with a screening covering background, projects, and motivation. Then there was a basic Python coding task with debugging, followed by a data foundations section focusing on Pandas for data cleaning, grouping, and handling missing data, and Matplotlib for plotting and customization. This included a hands-on exercise loading, processing, and visualizing a dataset. Next was an ML and PyTorch section covering PyTorch basics like tensors, autograd, and training loops, building and explaining a simple neural net, and discussing optimizers, overfitting, and regularization. A significant portion was dedicated to Transformers (75 mins), covering the attention mechanism, architecture, and using Hugging Face for tokenizers and pretrained models, including a case study on fine-tuning BERT for classification. Finally, the RAG design was explored, covering the retriever and generator concept, a pipeline with embeddings and a vector DB, and use cases like Q&A over company docs, along with discussions on scalability, hallucinations, and retrieval quality. The final round involved an end-to-end design of a RAG assistant for financial documents, and behavioral questions about teamwork, ownership, and learning mindset.
- If you were building a customer support assistant for a telecom company to answer queries like, “How do I upgrade my data plan?” or “What are the international roaming charges for country X?”, how would you approach the data ingestion task, considering the company has PDFs, FAQs, and call transcripts, and how would you preprocess and store this data for retrieval?
- For a retriever design in this system, what kind of embeddings and vector database would you choose, and what is your reasoning behind those choices?
- Regarding generator integration, how would you connect the retriever with a transformer-based model like GPT, BERT, or LLaMA to ensure accurate answers?
AI Fellow
The interview covered the pre-requisites of AI. Questions from data structures, mathematics, statistics, database, and basic python were asked in the interview. The interview is generally short about 10-15 minutes, or might go long depending upon the interviewer.
- Can you explain eigen vectors and eigen values?
- What are the pre-requisites for AI?
- Can you answer questions about data structures?
AI Fellow
It was a super friendly chat with the interviewer, and it wrapped up in exactly 10 minutes. We dove into some Python concepts like decorators, OOP, and static methods. Also touched on basic ML stuff like precision and recall, and some linear algebra topics such as vectors and eigenvalues.
- Could you tell me what static methods are in Python?
