I applied online. The process took 2 weeks. I interviewed at Meta in Mar 2022
Interview
Letter -> HR call -> Coding Interview -> System Design and stuff.
A lot of letters and notifications, a platform for preparing for the interviews and other cool stuff; hiring process is on the next technical level when compared to my other experiences.
The saddest thing is that you have no detailed feedback; it is either "everything is good, we're keeping moving" or "sorry to tell you you're not a fit". When I asked specifically to provide a somewhat detailed feedback on what went right and wrong on Coding Interview, I got an "NDA" answer or a close one. So it does seem to me that though I did solve the problems suggested I somehow didn't fit.
Interview questions [1]
Question 1
1. "Write a code telling wether a string is a valid number". Some basic examples are given, but you can dig in by giving your own examples of complex bad and good cases, like: "- .5" or "001", etc. Mostly depends on your fantasy
2. "Given a binary tree with unique values in nodes, for a query of two different nodes find the lowest common ancestor in this tree". Given the tree == given the root. A tree is a DAG, so no back edges from children to parent presented (but you are supposed to think of it and ask things like that, I presume)
The technical round hit me with a classic array manipulation problem: moving zeroes to the end without disrupting the order of non-zero elements. As I tackled it, I felt a wave of familiarity wash over me; I had just practiced a similar challenge on PracHub. The rest of the interview followed a straightforward path, with some easy behavioral questions sprinkled in. Overall, it felt very easy, but I wasn’t quite the right fit for what they needed, so I didn’t receive an offer.

Question 1
Move zeroes in an array to the end while keeping non-zero element order, in place
1 leetcode med, 1 leetcode hard. make sure you know your DSA and leetcode questions. I wasn't able to get an offer bc i didnt complete the second question. Got a reply 2 days later saying they would move on
I applied online. I interviewed at Meta (Menlo Park, CA)
Interview
It's honestly striaght from leetcode tagged
There are no surprises if you do tagged you would be good and do well.
System design is much harder. Would recommend using hello interview.
