I applied through a staffing agency. The process took 2 months. I interviewed at Meta (Sacramento, CA) in Oct 2024
Interview
Had 3 round of interviews, first with the Hiring manager and 2 with the team, The overall interview process was easy but in the end when the time came to let me know if I got an offer or not, they mentioned that they have a hiring freeze.
Interview questions [1]
Question 1
Questions were related to my past work experiences and projects. There were Leetcode questions and questions on the hardware technology that the team was using/working on.
I applied online. The process took 2 weeks. I interviewed at Meta (Menlo Park, CA) in Dec 2025
Interview
Interview process went well, the overall logistics were clear and concise. I felt like the hiring manager interview round is very deep dive into technical questions. I didn’t do great as I wanted since this was slightly challenging to answer precisely, I was able to successfully work through the questions but Hiring Manager had higher expectations.
