Soft interview with HR. Then interview with their "head of education" (??). All the questions were about implementation details of algorithms that I use. Afterwards got rejected without even getting a hard technical interview. I asked their recruiter for feedback, never got an answer. To me this behavior is consistent with that of a company interviewing in order to get information on their competitors. Avoid.

The interviewers seemed intent on probing for detailed insights into the algorithms and methodologies used at my current company, under the guise of exploring my past experience, while only briefly asking about finance.
