I applied through an employee referral. I interviewed at Meta
Interview
I interacted with at least 20 companies in the bay area. All of them are high tech companies and some of them are unicorns. Facebook's interview experience ranks as number 1 from all of them. Period! Although this time, due to timeline issues, I have to cancel the DS interview in the middle of the process but i've been through another position till onsite. Interview process can be stressful and sometimes even depressing. Thank you so much for making the interview process so smooth and make everyone feel important, not like the other giant company that drag the process to months. I love all recruiters that I interacted through out the process from Facebook. Please give them Kudos and love. Thank you Facebook recruiting team!
Interview questions [1]
Question 1
Just review the prep materials. It basically covers everything
Tough interview overall—definitely not what I expected. The technical rounds were intense, particularly when they had me design an A/B test for the News Feed ranking algorithm. I had to discuss metrics and sample sizes in detail. Lucky for me, the time I spent on PracHub right before the interview helped me nail that deep-dive question as it mirrored what I practiced. The behavioral questions felt standard but were still challenging. After a whirlwind process, they extended an offer, which I happily accepted.

Question 1
Design an A/B test to evaluate a new ranking algorithm for the Facebook News Feed. Walk through metric selection (engagement, time-spent, MSI, well-being), unit of randomization given network effects between friends, sample size and power calculations, how you'd detect novelty effects vs. true lift, and how you'd handle a guardrail metric regressing while the primary metric is up.
Total 7 rounds: first round for resume screening, second for technical screening, then for on-site virtual with 4 interviews back to back, then hiring manager round after team matching and then salary negotiation with HR
