“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 Pandas Developers Interview Questions
Pandas Developer interview questions for data wrangling
What’s your experience using Pandas for data manipulation?
Look for advanced DataFrame operations, indexing, and efficient data transformations.
How do you optimize Pandas operations for performance?
Expect vectorization, chunk processing, and avoiding unnecessary copies.
How do you handle missing or inconsistent data in Pandas?
Look for imputation, filtering, and type conversion strategies.
What’s your approach to merging and joining large datasets in Pandas?
Expect efficient joins, merge keys, and handling memory constraints.
Describe a project where Pandas streamlined data analysis.
Look for faster insights, cleaner pipelines, and reproducible workflows.
Memory explodes when joining two big DataFrames—solution?
Expect categorical downcasting, chunked merges, and joining on indexed, typed keys.
Groupby is painfully slow—how do you speed it up?
Look for vectorized precomputations, transform vs. apply tradeoffs, and using nunique/agg wisely.
Timezone-naive timestamps cause bad metrics—fix?
Expect tz_localize/tz_convert pipeline, explicit UTC storage, and robust parsing via to_datetime.
CSV ingest is the bottleneck—what’s your approach?
Look for dtype hints, usecols, engine choice, chunksize pipelines, and parquet migration.
Inconsistent schemas across files—how do you normalize?
Expect column mapping dicts, union-safe merges, and schema validation before concat.
Tell me about debugging incorrect aggregations in Pandas.
Expect identifying grouping logic errors, datatype mismatches, or index issues.
Describe resolving performance bottlenecks in Pandas data processing.
Look for vectorization, chunking, or using `categorical` types effectively.

Expect addressing mismatched keys, null handling, and column name collisions.
Share an example of cleaning messy data before analysis.
Look for applying `str` methods, regex, and `.apply()` for custom transformations.
How have you handled memory errors with large datasets?
Expect downcasting dtypes, processing in batches, and using Dask integration.
- Overuses loops instead of vectorized operations
- Fails to handle missing or malformed data
- No attention to memory optimization for large datasets
