The Trade Desk Software Engineer interview questions

The interviews involved a rather lengthy take home test. Unfortunately I was matched with technically incapable interviewer on the problem, who had trouble understanding basic facts about integers in programming and how the modulo operator works. The specifications of the programming task is not very suited for all the programming languages they offer (for example having to support multiple concurrent threads in python). However, the programming test did not take this into account in anyway, which created quite a bit of confusion and frustration with the task for me.

There was a HackerRank-based coding-test for screening. After that was followed up with HR for next steps which involved having a video-interview with one of the engineers. It was non-technical, more of them learning more about me & me learning about the position and company. Though he seemed distracted at times, he was cheerful & good to talk to. I was given a coding exercise with good amount of time to complete. IMO it was a good step since the question tested for important concepts & foundational knowledge while giving you ample time to work on it, as opposed to traditional interviews. The following steps supposed to be after that were a discussion with the engineers about the assignment followed by an on-site. Unfortunately I was unable to submit the assignment due to whatever reasons, so I cannot say how my rest of the experience would have been. But I wanted to mention that they were patient and understanding during the process, giving me time & space required. I appreciate that especially since there are many companies where recruitment process seems so impersonal & robotic due to the attitude of the HRs, interviewers, policies, etc.
