I applied through a recruiter. I interviewed at X in Oct 2020
Interview
Got LinkedIn message from a recruiter, and he setup initial phone call with a project manager to discuss about my work, resume and technical questions but no coding. Video call lasted for about hour and interviewer asked me some hypothetical questions about how to solve particular problem. I offered few solutions, we went onto deep with one and explained pros/cons of it. After few days I asked my recruiter about what happened and never heard back from anyone at twitter. What a colossal waste of time. Very unprofessional of them to go dark and not even replying back with any feedback.
I applied online. The process took 3 weeks. I interviewed at X (San Francisco, CA) in Sep 2024
Interview
Not complicated, multi layered / multi round, many questions asked about prior work history in machine learning, were looking for young, hungry, experienced candidates. Easy for them to find and sift through since they're a premier place to work at for this application.
Interview questions [1]
Question 1
Asked if I was willing to work at the office at all times, essentially live there, come to find out they're moving to TX and thus I can't follow them.
Phone screen at Twitter for MLE II. One hour coding interview with a software engineer on the same team. Spent the first 10 minutes going through the resume and the rest 45 minutes doing leetcode questions.

Question 1
Leetcode question with minor change. Apply DFS/BFS to traverse a matrix. Follow-up question is another leetcode question that requires knowledge of prefix tree.
The interviewer gave me a coding question and ask me to solve it. I told him my idea first and then start writing code. After I finish the basic solution, he asked me to optimize it. Then he asked me about time and space complexity.
