1. Phone Screen with the Director. 2. Online technical interview with an engineer. 3. Take home test/assignment. 4. In-person interview in their New York office. The in-person interview was split into 3 sessions: 1. A fairly straightforward coding challenge. 2. A fairly abstract design challenge. 3. Interpersonal interview with the Director. The online technical interview and on-site coding challenge were pretty straightforward. For the on-site challenge, I was offered the option to bring my own laptop, complete on equipment provided by them or use a whiteboard. I chose to bring my own laptop but was only allowed the whiteboard option, which is one of my weakest interview methods. I was neither offered lunch before nor taken to dinner after the on-site interview series. I live in Seattle so the HR department scheduled all airline and hotel arrangements. My flight from Seattle to New York, booked through Datadog, arrived at midnight the day before the interview so I did not reach the hotel until 3AM and as a result entered the interview process with only 2 hours sleep within a 30 hour period after 13 hours of travel. The returning flight was scheduled at 9AM the morning after the on-site interview cycle. I would suggest any potential applicant schedule their own transportation to the on-site interview as sleep deprivation, in my opinion, was a major factor in my failure to effectively answer some of the non-technical questions and complete, within a reasonable amount of time, the technical portions of the on-site coding challenge. Overall, the interview process was positive, as all of the interviewers were cordial and seemed to be familiar with th interview materials (questions, challenges, etc.). None of the interviewing engineers seemed to know much about my past experience and the on-site interview with the Director was the most positive. An initivation to the on-site interview is worth accepting if for no other reason than to see the view from their New York Times building office. :)
