“With Lupa, we rebuilt our entire tech team in less than a month. We’re spending half as much on talent. Ten out of ten”
“We scaled our first tech team at record speed with Lupa. We couldn’t be happier with the service and the candidates we were sent.”
"Recruiting used to be a challenge, but Lupa transformed everything. Their professional, agile team delivers top-quality candidates, understands our needs, and provides exceptional personalized service. Highly recommended!"
“Lupa has become more than just a provider; it’s a true ally for Pirani in recruitment processes. The team is always available to support and deliver the best service. Additionally, I believe they offer highly competitive rates and service within the market.”
"Highly professional, patient with our changes, and always maintaining clear communication with candidates. We look forward to continuing to work with you on all our future roles."
“Lupa has been an exceptional partner this year, deeply committed to understanding our unique needs and staying flexible to support us. We're excited to continue our collaboration into 2025.”
"What I love about Lupa is their approach to sharing small, carefully selected batches of candidates. They focus on sending only the three most qualified individuals, which has already helped us successfully fill 20+ roles.”
"We hired 2 of our key initial developers with Lupa. The consultation was very helpful, the candidates were great and the process has been super fluid. We're already planning to do our next batch of hiring with Lupa. 5 stars."
"Working with Lupa for LatAm hiring has been fantastic. They found us a highly skilled candidate at a better rate than our previous staffing company. The fit is perfect, and we’re excited to collaborate on more roles."
"We compared Lupa with another LatAm headhunter we found through Google, and Lupa delivered a far superior experience. Their consultative approach stood out, and the quality of their candidates was superior. I've hired through Lupa for both of my companies and look forward to building more of my LatAm team with their support."
“We’ve worked with Lupa on multiple roles, and they’ve delivered time and again. From sourcing an incredible Senior FullStack Developer to supporting our broader hiring needs, their team has been proactive, kind, and incredibly easy to work with. It really feels like we’ve gained a trusted partner in hiring.”
Working with Lupa was a great experience. We struggled to find software engineers with a specific skill set in the US, but Lupa helped us refine the role and articulate our needs. Their strategic approach made all the difference in finding the right person. Highly recommend!
Lupa goes beyond typical headhunters. They helped me craft the role, refine the interview process, and even navigate international payroll. I felt truly supported—and I’m thrilled with the person I hired. What stood out most was their responsiveness and the thoughtful, consultative approach they brought.
Talking about Lupa, I would say: these are the people you want to work with. They understand what consultancies are like. They understand that they could work for a month on a req, only to have it pulled because a client contract didn’t go through. You understand our business model, and that is invaluable.

Top RAG Developer Interview Questions
Questions to ask RAG Developers in technical interviews
How do you implement Retrieval-Augmented Generation in production?
Look for explanation of retrievers, vector databases, and prompt construction. Bonus if they’ve used LangChain or similar orchestration frameworks.
What embedding models have you worked with?
Expect OpenAI, SentenceTransformers, Cohere, or custom-trained models. Look for understanding of trade-offs in vector quality and size.
How do you manage document chunking and context windows?
They should discuss chunk size tuning, overlap strategies, and optimizing for retrieval quality.
What vector database platforms have you used?
Look for Pinecone, Weaviate, FAISS, or Qdrant. Bonus if they can discuss indexing, filtering, and scaling.
How do you evaluate the quality of RAG responses?
Expect mention of grounding checks, factual consistency, retrieval accuracy, and latency benchmarks.
How do you debug hallucinations in a RAG system?
Look for inspection of retrieval quality, prompt clarity, and source document alignment with generated output.
What’s your approach when retrieval returns irrelevant documents?
Expect query reformulation, vector database tuning, re-ranking strategies, and improved chunking techniques.
Describe how you monitor the relevance of RAG responses in production.
Expect mention of human feedback loops, embeddings drift detection, or semantic similarity scoring.
How do you troubleshoot latency in large-scale RAG pipelines?
Look for batched queries, optimized embeddings, and distributed retrieval systems.
What do you do when generation contradicts retrieved sources?
Expect use of grounding logic, answer masking, or formatting that highlights original source evidence.
Describe a time you collaborated across teams to ship a model to production.
Expect coordination with MLOps, product managers, and devs—plus ownership of handoff success.
Tell me about a time your deployment failed—what did you learn?
Look for ownership, alerting improvements, and resilience through iteration.
How do you handle tension between research and engineering constraints?
Expect pragmatism, backlog balancing, and milestone planning.
Describe how you respond when metrics stop improving.
Expect root cause analysis, feature engineering pivots, or label strategy reviews.
How do you manage technical debt in ML pipelines?
Look for scheduled cleanup, modular design, and team-wide knowledge sharing.
- Misunderstands vector search performance trade-offs
- Fails to optimize retrieval for domain-specific needs
- Uses generic chunking/tokenization strategies blindly
- Weak grasp of latency and scoring mechanisms
- Overlooking fallback strategies for poor results

Book a Free Consultation
I help companies hire exceptional talent in Latin America. My journey took me from growing up in a small town in Ohio to building teams at Capital One, Meta, and eventually Rappi, for which I moved from Silicon Valley to Colombia and had to recruit a local tech team from scratch. That’s where I realized traditional recruiting was broken, and how much available potential there was in Latin American talent. Almost ten years later, I still work closely with Latin American professionals, both for my company and for clients. They know US business culture, speak great English, work in the same time zones, and bring strong skills and dedication at a better cost. We have helped companies like Rappi, Globant, Capital One, Google, and IBM build their teams with top talent from the region.
