I applied online. I interviewed at TikTok (Sydney) in Mar 2023
Interview
During the first round interview, I was asked to explain a couple networking and concurrency concepts, along with answering follow-up questions and providing code demonstrations. Subsequently, I was given a medium-level LeetCode question to solve. I was short in time so nervous and didn't complete it. Overall, my performance wasn't great, and not getting an offer was understandable.

Deep dive into past projects, anything that is relevant in software development would be asked, not only backend development. Then the interviewer posed questions about basic concepts and terminologies like locks, process management, memory management, database sharing etc. Ended with a medium Leetcode problem.
