Dataminr Senior Software Developer interview questions

1st round: Phone call with recruiter. Background information, job details, salary expectations. 2nd round: Take home coding challenge. Submitted in mid December. I contacted the recruiter in early January to ask for an update, and whether a code review interview would be scheduled. No response. I received a generic email a few days later stating that the process had ended. I again contacted the recruiter to ask for feedback as to why. No response. Very poor communication and organisation. I would highly advise against applying here.
