I applied through an employee referral. The process took 1 day. I interviewed at The Trade Desk (Ventura, CA)
Interview
The interview process has multiple steps, because I was a referral from another engineer on the team I was able to skip one of the steps;
1) Informational interivew, they spend time explaining the industry, the company, the engineering team and their development process.
2) A real take home engineering test. This is a much better way of assessing my skills then having 10 minutes to write a small algorithm on a white board. If I'm going to write software for a living, let me show that I can do it. This was followed by a review of my design and implementation. Sort of like a code review.
3) A phone interview with one of their senior engineers.
4) In-person interviews in Ventura, CA.

Other Senior Software Engineer Interview Reviews for The Trade Desk
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).
