“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 7 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.

Top AI ML Developer Interview Questions
Key things to ask when hiring an AI ML Developer
What’s your process for selecting and tuning ML models?
Expect mention of cross-validation, hyperparameter tuning, and model selection criteria. Look for awareness of overfitting and interpretability.
Can you explain feature engineering in one of your recent projects?
Look for thoughtful use of domain knowledge, transformation techniques, and automated feature selection tools. Depth of reasoning is key.
Describe your experience with model deployment in production.
Candidates should mention APIs, Docker, CI/CD pipelines, and monitoring. Bonus if they’ve used MLOps tools like MLflow or SageMaker.
How do you handle imbalanced datasets?
Strong answers may include SMOTE, class weighting, resampling strategies, or evaluation with appropriate metrics (AUC, F1-score).
What metrics do you use to evaluate model performance?
Expect a tailored answer depending on the task (classification, regression). They should mention precision/recall, RMSE, ROC curves, etc.
How do you handle model underperformance after deployment?
Look for evaluation metrics, dataset drift analysis, and retraining procedures.
Describe a time when your model delivered unexpected results. What did you do?
Expect answers involving debugging data preprocessing, feature leakage, or labeling inconsistencies.
How do you troubleshoot training instability or loss divergence?
Look for learning rate tuning, architecture adjustments, or gradient clipping.
What’s your approach when data for a critical feature is missing or corrupted?
Expect imputation strategies, feature elimination, or data reconstruction using proxies.
How do you balance model complexity with interpretability?
Expect experience with interpretable ML models or tools like SHAP, LIME, and stakeholder-driven choices.
Tell me about a time a model you built failed in production.
Expect details on investigation, retraining, and communication with impacted teams.
How do you handle conflicting feedback from stakeholders on model outputs?
Expect prioritization strategies, data-backed communication, and iterative updates.
Describe a collaborative project where you had to integrate with engineering or product teams.
Look for examples of teamwork, shared timelines, and handoff practices.
How do you stay motivated when model training yields minimal improvement?
Expect signs of resilience, hypothesis reformulation, and long-term problem-solving mentality.
What’s an example of a difficult decision you made when building a pipeline?
Expect trade-offs involving scalability, latency, or interpretability, and rationale shared clearly.
- Weak grasp of model evaluation techniques
- Failure to validate data preprocessing pipelines
- Minimal exposure to production ML workflows
- Lack of reproducibility in experiments
- Dismissive of ethical or bias concerns
