I applied online. The process took 2 weeks. I interviewed at Dataminr (New York, NY) in Mar 2015
Interview
Applied on their official website and got a phone call from HR. The HR call is for get to know your background better.
And then a phone call for technical stuff. One is write a function to get the median number from a dynamic number stream. (Two heaps) The other one is spiral matrix.
Two days later got the feed back and sheduled for an onsite interview. Talked about your resume and then coding.
1. Find out the k nearest position from a given spot on a map.
2. A maths problem, binary search is enough.
Interview questions [4]

One is write a function to get the median number from a dynamic number stream.
I applied online. The process took 2 weeks. I interviewed at Dataminr in Apr 2025
Interview
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.
Initial phone screening followed by 1 hour technical screening consisting of leetcode style problems. Next step is 3 rounds consisting of 2 more coding rounds and a behavioral round with the hiring manager. Overall pretty standard interview process but poor communication from the recruiter. After the final round I was completely ghosted, reached out to recruiter multiple times to get no response.
