I applied through a recruiter. I interviewed at The Trade Desk (London, England) in Apr 2023
Interview
Bad experience: was first informed that I had past and then was rejected after a few days. The interviewer was inexperienced: gave a very easy question which I completed quickly. He explicitly stated that pseudo code was fine, did not raise any concern and did not take my answer. However, he later criticized the quality of my answer.
Interview questions [1]
Question 1
very basic coding problems plus some quick questions on old school techniques
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
Interview questions [1]
Question 1
problem solving questions that might not need to execute the code but need to explain, need to debug an existing codebase, a Leetcode medium algo question, system design question

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).
