I applied online in April, 2018. The whole process took 4 weeks including: one phone screening, one technical phone interview and an one-day onsite interview with 5 back-to-back individual interviews. Technical phone interview: standard coding questions that are similar to questions in Leetcode. One-day onsite interview with 5 back-to-back sessions. The questions essentially covered the following: reviewing my background and experience, coding questions, machine learning design questions, motivations to join Dataminr and brain-teaser puzzles. The questions asked in the onsite interview were quite difficult, in my opinion, especially when you have to answer some open-ended questions. One week after the onsite interview, Dataminr let me know the result of the interview and decided to hire me.

Recruiter seemed a bit rushed/reading from script, asked about some very specific things from work experience (not in resume, seemed like they were looking for key words for me to mention). At time of interview the company seemed to be in a hurry to hire. Interviewer was friendly and engaged in the interview - LeetCode/many edge cases type question.
