Timeline: 8/19 - OA 9/23 - First round technical invite 10/2 - First round 10/3 - Second round technical invite 10/13 - Second round 10/14 - Third round technical invite 10/20 - Third round 10/22 - Received email saying decision will be made in 1-2 weeks 11/15 - Received email saying headcount is full (after 4 weeks) Interviews: All 3 rounds were an easy-medium leetcode question split into multiple parts, going from easy to medium. Topics covered for me were basic data structures, recursion and matrix math. Super nice interviewers and very fun questions but recruiters were horrible with the timelines IMO, knew multiple people waiting for >2 weeks after final and recruiters do not reply to emails at all. Headcount seems to be around 2 for the AU region. Please don’t dm to ask interview questions as an NDA was signed.
