Two Sigma interview questions

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.

I was asked to come in for a three hour interview that ended up being closer to four hours. I met with five people, pretty much everyone that I would being working with on a regular basis within the company. The second round consisted of a redesign project. This part of the process revealed a bit of disorganization. The company doesn't have very many designers, and for that reason is relatively new at conducting designer interviews. I was given "very positive" feedback on my redesign as of Monday, and told that they were just waiting on more candidates, but saw that the job had been reposted and found out that they weren't "moving forward with my candidacy" by Thursday. Just seemed a little disingenuous to me. Overall a very slow moving process by New York standards.
