They asked me not to reveal any questions.
There was for instance a basic coding challenge interview at the start. But a thing I'll mention is, for a high-level company like FB, there was an odd obsession with basics, when people don't work that way -- it's not that it's irrelevant, it's better to be solid than not, but it's a tiny piece of the puzzle that's gating prospective hires. It was strange to not be asked the types of questions that would indicate actual capacity to innovate, manage, etc. I would have only done that kind of challenge for maybe a fresh graduate, not someone who's done real work.

Q1> reverse a inked list and print the reversed list . Ex: 1->2->3 , result:3->2->1 Q2> divider a number by another number and print result and remainder if any. you are not supposed to use "/" and "%" operation
Suppose you have an array of positive and negative integers. Given X as input, find two numbers that add up to X.
What are different types of interrupts?
Write a function that takes an integer and prints out the digits separated by commas. Example, pass in 345 print out 3,4,5
Find the numbers occur odd times (e.g. 1,3,5,7,...) in the given array. e.g. { 2, 2, 1, 1, 1, 4, 4 } You should print 1.
How would you implement a sparse array (key could be any integer, but only a few would be used) with limited memory.
