I applied through a recruiter. The process took 3 weeks. I interviewed at Meta in Jan 2025
Interview
I had a total of four interview sessions: two focused on coding, one on behavioral questions, and one on system design. Each interviewer was kind and professional, creating a welcoming atmosphere. The questions were fair and well-structured, making them reasonable to answer. Overall, it was a positive and balanced interview experience.
