I applied through a recruiter. The process took 1 day. I interviewed at Meta in Sep 2017
Interview
it was a phone screen with Data Engineer. He was very polite and even helpful. When I stumbled he was gently suggesting a correct approach. I was stressed out regardless. :)

Question 1
30 min for 3 SQL questions: all of them used group by and outer joins
30 min for 3 Java questions: all of them are covered here at GlassDoor ( single array loop; strings & substrings)
Begins with an application review and recruiter screening, followed by a technical phone interview that assesses SQL, data modeling, data warehousing, ETL processes, and coding skills in languages such as Python or Java. Successful candidates then proceed to onsite or virtual interviews, which include multiple rounds covering coding, system design, data architecture, problem solving, and behavioral questions.

I applied online. I interviewed at Meta (New York, NY)
Interview
Prepare technical concepts, and practice previously asked questions as much as you can find online. 4 rounds in the total process. It's easy as long as you just practice a LOT.
