“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.

Top Qt Developer Interview Questions
What to ask during Qt Developer interviews
What experience do you have with Qt's signal and slot mechanism?
Look for candidates who can explain how signals and slots are used for communication between objects in Qt, and who demonstrate practical experience in implementing them. Understanding the use of auto-connections and the differences between direct and queued connections can also indicate deeper knowledge.
Can you describe how you have utilized Qt's Model/View architecture in your projects?
Candidates should be able to discuss specific instances where they used the Model/View architecture to separate data from its representation. Look for understanding of custom models and views, and how to optimize performance with large datasets.
How do you approach debugging and profiling Qt applications?
They should discuss tools like Qt Creator’s debugger, Valgrind, or QML Profiler. Practical experience with identifying bottlenecks, memory leaks, or UI inefficiencies indicates they can efficiently optimize applications.
What is your experience with QML and how do you integrate it with C++ in your Qt projects?
Look for familiarity with QML for designing UIs and how they connect QML with C++ logic. Candidates should explain using context properties, invoking C++ methods from QML, and potential pitfalls to watch for.
How familiar are you with cross-platform development using Qt, and what challenges have you faced?
Seek examples where they effectively used Qt for cross-platform applications. Understanding of platform-specific nuances and how they handle UI differences or hardware access can show adaptability in diverse environments.
Can you describe a challenging problem you faced in a Qt project and how you resolved it?
Look for a candidate who identifies specific issues they’ve encountered, articulates the steps they took to analyze the problem, and explains their solution. Assess whether they demonstrate perseverance and logical thinking.
How do you approach debugging when you encounter a crash in a Qt application?
The candidate should outline a systematic approach to debugging—starting from reproducing the crash, using tools like Valgrind or GDB, and analyzing stack traces. They should show resourcefulness and attention to detail in their approach.
Have you ever needed to optimize a Qt application for performance? What approach did you take?
Look for an understanding of profiling tools and techniques like QML optimizations or reducing render passes. The candidate should focus on both identifying bottlenecks and applying effective optimizations.
Describe a time when you needed to integrate Qt with external libraries or systems. How did you handle it?
The response should highlight the candidate’s ability to work with external APIs, manage dependencies, and ensure seamless integration. Assess their problem-solving skills in working with different technologies and frameworks.
What strategies do you use to maintain code quality and manage technical debt in your projects?
Consider whether the candidate employs techniques like code reviews, automated testing, and refactoring. They should demonstrate awareness of long-term project integrity and proactive problem-solving in maintaining code quality.
How do you handle tight deadlines when working on complex projects?
Look for evidence that the candidate stays calm under pressure and remains focused on priorities. They should discuss techniques they use for managing stress, such as breaking tasks into smaller steps or effective time management strategies.
Can you describe a time when you successfully collaborated across teams?
Listen for examples of proactive communication and collaboration, showing adaptability and understanding of different perspectives. The candidate should demonstrate how they integrated ideas to achieve a shared goal.
How do you ensure clarity when conveying technical concepts to non-technical stakeholders?
