I am a senior Data Engineer. Recently got rejected at Apple’s onsite as could not solve two Leetcode problems. Other interviewers were impressed by my Big Data skills( at least from their body language) as that’s my day-to-day job. So for FAANG Data Engineering is Leetcode a must no matter how good you are in coding for Data Pipeline problem using Spark/Airflow/Kafka/EMR/Lambda etc ?Asking as I have a 14 hrs job which I enjoy a lot as I like to solve meaningful data analytics problems and to build reusable framework for ETL but are those skills of lesser value than leetcode ?#dataengineering #onsite #Data #Hadoop
