Q: In the Python programming assessment, I encountered questions that assessed knowledge about the mutability of data structures like tuples, lists, and dictionaries. Additionally, there were Object-Oriented Programming (OOP) questions. The coding portion involved real-time challenges, including tasks such as checking for palindromes, removing elements from data structures, and performing 3x3 array operations, such as calculating row sums, diagonal values, and column sums—all without utilizing external packages like NumPy.

L1 round has questions on SQL, Hive, Python, Spark.Cleared the first round. L2 was F2F where i was asked to write code on Python. SparkCore, SQL, SparkSQL. The question were to read the files and find out max sold product basis of each product. And then was F2F which was on Hadoop: Rack Awarness Map and FlatMap Map and Reduce Partititon and Bucketting. Could not answer 2 questions on Hadoop Architecture.
