Hi Manish, I have one question. I am technically sound in Java programming language but not having enough knowledge in python. Is it okay if we write the coding questions for Data Engineering interviews in our preferred language or do we need to write exclusively in Python?

Q.10 for ind in range(1,len(l)): if l[ind-1] 7: l.insert(ind,a) break print(l)

Hey Manish Were there any screening round for you before the technical round

Hello can please share SQL question as we’ll

how to decide shuffle partition, could you please explain how do you ans this question in interview

@manish_kumar_1

Жыл бұрын

It depends on data. So please ask the interviewer how you data looks like. There can be a case that he is partitioning the data based on Id column and one Id has way to much data than the other id's. So in that case salting will help. General thumb of rule for number of shuffle partition is to keep upto 4x time number of cores you have.

this was for fresher or for experienced person? Of how many year of experience was this for?

there is no fact table mentioned in this video .. generally in sql we follow normalisation ...fact table concept is more applicable in snowflake schema which is dw concept .
