Hi,

Can anyone provide any info on preparation and range of questiosn(easy/medium) for FB data engineer in analytics position? I am focussing on below

sql - Are leetcode sql questions enough?
python - Are arrays and string enough from leetcode?
data modelling

For data modelling , is there any resources to learn? What type of questions will they ask in data modelling. Are we expected to create dimension models for a case study? What other areas should I cover?
