I applied online. I interviewed at TikTok (Sydney) in May 2024
Interview
They first asked some questions related to my current job and then gave a leetcode medium question to solve. Asked a lot of SQL questions such as "How do I make an SQL query more efficient?". The interviewer I had was nice.

Interview
Went through two out of three interviews with TikTok, in both they asked basic concurrency, networking and language specific questions as I was going for a C++ role.
They also asked Leetcode Medium questions in both interviews.
Really poor organisation from the HR team, with the main online interview being performed in their car with no camera. Maybe this was an outlier from others but still hurt my experience
