Ho presentato la mia candidatura tramite un selezionatore. La procedura ha richiesto più di una settimana. Ho sostenuto un colloquio presso EPAM Systems (Poona) nel mese di mag 2024
Colloquio
The first round involved an online assessment on Codility which had 20 MCQs, one SQL and one DSA problem,
The second round was a technical interview where most of the questions were about Spark. I did not do well, but the quality of the questions was excellent.

Colloquio
The interview process went for more than 2 hours 30 minutes. But it was a good experience.Got to learn new concepts and helped me prepare better for my further interviews. Initially it was about project, python, sql, pyspark and AWS related services.
First, I had a meeting with HR to know more about the company and basic aspects of the position. Then, a technical interview. Later on, I had a meeting with HR again to know my results and to check the offer. The process took around one month.
