I applied online. The process took 4 weeks. I interviewed at Meta in Nov 2011
Interview
Got an email from Facebook that it sees my resume and wants to give me an interview.
But first get a call from the recruiter to discuss about my intention.
The phone lasted like 10~15 mins, just asking about my previous experience, graduation date, and my team choice.
Then the 1st phone interview was scheduled. It is probably one of the hardest, thinking that they want to cut down as many people as possible.
After that was the 2nd, then on-site.
On-site, I met like 6 others Google Interns, and then we had a tour of the office, lunch, then 3 consecutive interviews.
Then I got the offer like 3 days later (cuz I told them I had other deadlines, so they made it fast).
They had a talk with one of my professor, who I wrote as the reference.
Interview questions [1]
Question 1
A period of time where users login and logout, given a sets of login and logout time pairs, write a function that can show the number of users online at any given time.
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
Unexpectedly, the first question in the technical round felt familiar. It was about finding a subset of strings with unique character concatenation — same problem I had worked through on PracHub a few days earlier. The interview included a recruiter screen followed by a rigorous pair of technical interviews where I tackled data structures and algorithms alongside system design concepts. After successfully answering a few more challenging DSA questions, I received an offer. The entire experience was intense but ultimately rewarding, and I happily accepted the position.

Question 1
Given an array of strings, pick a subset whose concatenation contains no duplicate characters, and return the maximum possible length of that concatenation.
Standard cookie cutter interview with a coding interview, a system design interview and culture interview. The coding part is basically leetcode. The system design is what you can find on many youtube videos. The culture one is more tricky as they want to see that you fit Meta's culture, not that you were doing great at your existing company. So skills like dealing with conflict without calling in managers is sought after.

coding: I forgot, sorry
system design: design ticketmaster
culture: talk about past project; when you disagreed with a peer; how I resolved dissagreements, etc.
