Ho presentato la mia candidatura tramite un selezionatore. La procedura ha richiesto 2 mesi. Ho sostenuto un colloquio presso Booking.com (Amsterdam) nel mese di feb 2019
Colloquio
Resume screening -> HR telephonic -> Hackerrank assignment -> bluejeans coding interview
HR is only told to seek answers as PBs of data being ingested!
HackerRanks is the most ugliest way to conduct interviews for data engineering

HR telephonic: How much data do you "ingest" daily? HR has no clue of differences b/w ingesting and processing. If you by chance say in GBs and TBs only and not PBs, you just marred your fortunes for a free trip to Netherlands.
Hackerrank most pathetic SQL questions, one ambigous python ques which are very, very easy to solve
Telephonic: HR doesnt know what exactly is the nature of interview and what topics to prep for, they tell you SQL/Streaming/Data Structures and ask 'Scala' functional programming crammed by heart!!
First there was coding challenge with 1 hour time which you do on your own, Then screening call in which you are asked general questions about your background and experience, then technical interview, then system design, and ultimately cultural fit.

The technical interview is Python only. In general not hard. First part is some Python coding with three sections. There is a second part which also has 3 parts but its about data aggregation and computing insight
Remote test, call with hr, followed by live coding session with fellow engineers, didn't make it further but good luck with the steps. Questions were not hard, I stressed too much

Colloquio
The first screening round consists of SQL and Python coding tasks. If you clear this screening round, you will be invited to the second round, which is an HR introduction call. During this call, the HR representative will discuss your motivation and assess your skills.
The third round is a live core Python coding session, where three data engineers will evaluate your Python programming abilities. The coding problem will be related to a booking platform, involving trip analysis queries that need to be implemented in Python.
The fourth round focuses on system design, and the fifth and final round is a behavioral interview.
