Submitted my resume online and heard back shortly after.
First round was a short data assignment you need to complete in two days. I made a mistake but was able to correct it after asking for feedbacks. They were kind enough to give me a second chance to move forward. So don't give up!
Second round was a 30-min call with the HR coordinator about my resume and background.
Third round was a group info session where the VP of product talked about the company and the DPA role. If you're in NYC you will be invited to the office; otherwise you will join via Zoom.
Fourth round was a much more complicated assignment and is also the most important part of the interview process. I needed to finish a report and send it back in a week. Took a lot of my time. After I sent in my report, there were 2 rounds of follow-up questions, each took about a week.
Final round was an onsite interview with 4 people - 1 engineer, 1 research analyst, the VP of product and one of the cofounders. Mostly behavioral and background questions. Worked through a small case with the VP.
Overall it was one of the best interview experiences I've had. They were very responsive and I got a good sense of what the job entails.
