I applied through a recruiter. The process took 4 weeks. I interviewed at Meta (Menlo Park, CA) in May 2019
Interview
1 hour phone screen;
SQL questions were fair but hard. The database schema has had 4 or 5 tables but the questions were related to one table only. In 30 min, I was able to answer only 2 sql questions instead of 3. In addition, answers with sub queries are not counted towards correct solution.
python/java coding examples are easily found glassdoor, but not SQL.

SQL:
1. given table products(product_id, brand_name,product_name, product_price), find brand_names with avg price > 3 and having more then 5 products

Starts with a screen, followed by leetcode style SQL+Python questions, Full loop of SQL, Python, SQL plus Python and lastly behavioural round. Every round is also an architecture round in some sense.
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.
