I applied online. The process took 3 weeks. I interviewed at X (San Francisco, CA) in Sept 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.
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.
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.
