I have my first round technical data engineering interview for Facebook in 2 weeks, I was wondering if any one has had any recent experiences in 2020. I know it's 5 SQL and 5 Python. Also heard that their questions has been changed from what's there in glassdoor. Can anyone throw some pointers on the preparation. Are they asking leetcode hard questions on algorithms or easy/ medium should cover everything. Are some questions outside from leetcode too?
