“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 Phoenix Developer Interview Questions
Questions to screen Phoenix Developer candidates
How do you manage application state in a Phoenix application?
Look for understanding of Phoenix’s state management tools. The candidate might mention using the Conn struct, Plug, or session storage for managing state. They should show proficiency in choosing the right tool for the task and understanding the implications on application performance.
What is your experience with LiveView, and how have you utilized it in projects?
Check if the candidate can communicate how they have used LiveView for real-time features in applications. They should demonstrate familiarity with LiveView's architecture and benefits, such as reducing JavaScript complexity while enhancing the user experience.
Can you explain the difference between a context and a schema in a Phoenix project?
Listen for an explanation that contexts serve as interfaces or boundaries in an application, separating logic, while schemas define the structure of data. This distinction is crucial for maintaining clean architecture and ensuring module boundaries are respected.
How do you ensure security within a Phoenix application?
The candidate should discuss strategies for securing a Phoenix app, such as protecting against common threats (XSS, CSRF), and using Plug for security measures. Experience with authentication and authorization libraries like Guardian can indicate further expertise.
What strategies do you use for testing in a Phoenix application?
Strong candidates will mention using ExUnit for testing. Look for discussions about writing comprehensive tests, including unit and integration tests. Familiarity with tools like Hound for browser testing can indicate a thorough approach to quality assurance.
Can you describe a challenging problem you encountered while working with Phoenix and how you resolved it?
The candidate should clearly outline a specific issue they faced, detailing the steps they took to diagnose and solve it. Look for their ability to articulate the problem-solving process, including any debugging tools or techniques they used.
How do you approach optimizing database queries in an Elixir/Phoenix application?
Evaluate the candidate's understanding of query optimization techniques, such as using Ecto for efficient queries, indexing, and understanding query execution plans. They should demonstrate both technical knowledge and practical application.
What strategies do you use to handle concurrency issues in Phoenix applications?
Look for a grasp of Elixir's concurrency model and how Phoenix leverages it. The candidate should mention using features like GenServer, Task, or other concurrency tools, showcasing their ability to design for concurrent processes safely.
How do you ensure reliability and robustness in your Phoenix applications?
The candidate should discuss their approach to writing tests, using Elixir's testing framework, and implementing fault-tolerant designs. Consider their emphasis on making sure the application can gracefully handle errors and edge cases.
Give an example of a performance bottleneck you identified in a Phoenix app and how you addressed it.
Assess their problem-solving process in identifying and alleviating performance issues. They should explain the tools they used for profiling and monitoring, the specific changes they made, and the impact of those changes on performance.
Can you describe a time when a project didn't go as planned? How did you handle it?
Look for candidates who show adaptability and resilience. Their response should demonstrate problem-solving skills and the ability to remain calm under pressure without resorting to blame-shifting.
How do you keep team members motivated during challenging times?
Evaluate if the candidate can identify specific strategies they've successfully used, such as giving constructive feedback or recognizing team achievements. Their response should show empathy and a collaborative spirit.
Tell me about a time you had to communicate complex technical information to a non-technical audience. How did you approach it?
Assess whether the candidate can simplify complex concepts without condescension. They should demonstrate the ability to tailor their communication effectively to different audiences.
Have you ever been in a situation where you had to resolve a conflict within your team? How was it resolved?
Seek responses that show active listening, empathy, and conflict resolution skills. A strong answer will highlight working towards a compromise or solution that benefited all parties involved.
How do you manage stress, especially when working on tight deadlines?
Consider candidates who have healthy coping mechanisms and proactive strategies, like prioritization or time management, to handle stress constructively without sacrificing team morale.
