I applied online. The process took 3 months. I interviewed at The Trade Desk
Interview
For three times, the manager forgot about my technical phone interviews. It was a terrible experience to waste 30 min every time to wait for the recruiter to contact the manager. The manager was either at a meeting or someone's desk being "busy". At the end, I have never spoke with the manager who was supposed to interview me. I would advice others to avoid this company.
Interview questions [1]
Question 1
Never had the chance to be interviewed due to manager being unavailable at the last moment (for three times).
60 mins - Algorithm questions. it was generally leetcode med level algorithm questions and they asked 2 questions. They were kind of rushing the interview and didn't seem like they cared about the interview.

I applied online. I interviewed at The Trade Desk (Sydney) in Oct 2025
Interview
I applied for a SDE position in Sydney AU. Online accessed + recruiter call + 4 rounds onsite rounds. The recruiter was super efficient and professional, some interviewers were very professional and friendly, however, the hiring manager had astonishingly bad manners, he gave an ambiguous and topic and didn’t collaborate or specify what aspects to focus on, as I continued to seek clarification, he became visibly frustrated and started yelling. Would recommend the company to improve the mental maturity of this hiring manager from HK before allowing him to become an interviewer again. The hiring manager's terrible manner explains why the same job has been posted again and again on Linkedin but never been filled over the last 2 months.
