I applied through a recruiter. The process took 2 months. I interviewed at Meta (Menlo Park, CA) in Mar 2019
Interview
Had 1 telephonic round - same questions as others have mentioned. Onsite had 4 rounds focusing on SQL, Coding and Product Sense.
Had I got the offer, I would have declined. The interviewers didn't seem like they like their jobs. They were rude. One person was the worst. He was condescending in his questions. He asked me what I would do in the first 90 days and after I answered, he mocks at me saying "thats it? You know 90 days is a lot of time". This guy was an engineering manager - gives you a good idea about the company and it's employees! I reported this person to the recruiter. I hope they take action. Also, I was told I didn't have strong SQL skills - well, I answered 14/15 of their interview questions and the same week I .interviewed for Amazon and got the offer. How can I get Amazon offer with my weak SQL?

Question 1
What do you wish to accomplish in the first 90 days?
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.
