hr reached out and briefly talked about interest and then sent out a data challenge with massive mta data. Each part of the challenge will take a long time comparing with other companies hiring process. And after I finished and submitted, no response for a two weeks. Then I reach out just get the response that we don't have a job match my background. No feedback about the data challenge. I do take some time working on it and am confident about most of the answers. They should at least give some feedback about the work I submitted.
