Ho presentato la mia candidatura tramite l'università. La procedura ha richiesto 4 settimane. Ho sostenuto un colloquio presso Boston Consulting Group (Milano) nel mese di mar 2025
Colloquio
First coding challenge on scikit-learn and pandas.
2 interviews. Both technical with real data analysis problems. The first had a plot showing 3 clusters of customers and some time series data.
The second started with a Fermi problem (how many tennis balls in the biggest church of milan) and then a tricky question about merging two very big databases about companies with the names of the companies that differed in the two.
