I applied through a recruiter. I interviewed at Meta
Interview
call with a recruiter followed by
online assessment , forty five min pre-screen online assessment was one and a half hour long in foo stages. each stage is increased in difficulty

The entire process usually takes 3–8 weeks, depending on scheduling and the specific role. Coding interviews heavily emphasize common DSA topics such as arrays, strings, trees, graphs, BFS/DFS, heaps, hash maps, and dynamic programming. System design becomes increasingly important for E4+ positions.

Question 1
Given an array of integers and a target value, return the indices of two numbers that add up to the target
Some recuireter spoke to me on phone and gave me the position's details and the interview details. She told me the following interview will have questions in Python and Sql.

Question 1
I will speak about the technical first step where I needed solving questions in Python (half an hour) and in Sql(half an hour).
I succeeded solving 2 SQL questions and 1 in Python.
Sql Part:
I was given 5 tables presented a library. But the main 2 and only tables I needed to use in the following questions were: copies and checkouts.
copies table : book_id,copy_id,condition.
checkouts table: copy_id,checkout_date,returned_date,renwed_count.
First Q:
Calculate the total number of books their condition is good and havent returned yet (it should be called "numbers_of_returned_books"). Take this total and return the books' precentage that their renewed > 2 (this should be called "pct_renewed").
The output should be - numbers_of_returned_books and pct_renewed.
Second Q:
They defined a value - lifetime_value. This value is calculated as : numbers of days since the day they were taken and returned. I was asked to bring the book ids their lifetime_value in top 3 books and pay attention their number of copies <=10 and their returned_Date is not null.
Python Part:
You are given a books list which cotains tuples. Each book in books list contains the book name and its score. For example:
list books = [("Agr",3),("bsa",2),("Agr",4),("mas",7)]
You need to return the highest score sum were given to the top 3 books in the list. You are not allowed sum the score number for a book twice.
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.
