A few rounds, with the first being an online coding test. Afterwards, a HR call with behavioural questions, and then finally a live technical interview where a leetcode medium question was asked. Correctly solved in the time with minor hints, so passed and given offer.
2 x 1-hour interviews with engineers from the company. Data structure/algorithms were asked with follow-ups. There was time at questions at the end to learn more about the company. The interviewer was nice and also guided me along.
I applied through an employee referral. The process took 2 months. I interviewed at Meta in Oct 2021
Interview
No return offer for interns. Based on their business needs, they only extend offers to the top performers (greatly exceeds expectations). But overall internship experience was good. Breakfast and lunch included.
