Colloquio
This was for the position of a Data Engineer in their core data group. Skills with Python and some C++ are expected. The interviewer began by telling me about the company. Next, he discussed my experience at my most recent two positions. After this, he proceeded with a technical interview on coderpad. I recommend practicing various dynamic programming questions using recursive solutions.

Domanda 1
Write a function to compute and return the number of ways in which to climb a flight of n steps, taking 1, 2 or 3 steps at a time.
Using Python, write a one-liner function to return a list containing only the unique elements of the given list. Order doesn't matter. Next, write a function to return an order-preserving list containing only the unique elements of the given list.

Domanda 1
Parsing strings
Math operations written with strings that you have to compute, Strings were not guaranteed to be valid.
Interviewer was not interested in my thought process or how I did the question, only if my code could pass the test cases.

Colloquio
Intense, 5 stages and very Python heavy, more core software engineering questions.
First stage asked me about decorator functions, context generator, Textual comprehension question where you convert stream of numerical numbers from an old phone keypad into letters, and to read a CSV file and find the max of a column.
No progression after getting 90%+ questions right.
