I applied through an employee referral. The process took 2 weeks. I interviewed at The Trade Desk (Denver, CO) in Apr 2018
Interview
The initial job application process was very slow. I sent in my application and didn't hear anything for weeks. But then they contacted me for a an-person interview. This was a meet-and-greet, no real technical questions. It was basically like a phone screen, but in-person. Then they gave me a coding exercise to solve on my own. I didn't pass this step in the interview process, but the hiring manager provided very helpful feedback to me on what I missed.
Call with recruiter, hiring manager, then schedule 4 technical rounds in the same week, 2 days after last technical section offer is released. Recruiter explained the process and reason behind each section very well, so I can expect what will happen and how I can prepare. Instructions within the round are very clear, interviewers are helpful and collaborative, so even the questions are not that easy the process is actually quite enjoyable and I feel respected. The process is very efficient, from they receive my application to offer accepted takes around a month

I applied online. The process took 2 months. I interviewed at The Trade Desk in Sep 2025
Interview
Online Assessment, followed by a Hiring Manager interview that was System Design + Behavioral. Didn't pass that stage, was not given a reason, but I assume it was the system design portion. Next stage would have been a loop (2 coding + 1 system design).
