Citrine Informatics Data Scientist interview questions

The process started with a phone screen going over my resume and general experience. There was a take-home data challenge afterwards, which was not too difficult. The final on-site interview was a full day event with 6 hours of interviews with all different people we would work with, including the CEO and COO. The questions were not very technically challenging but was a very lengthy process.

Recruiter was great and communicative. However, after spending a week of hard work on the take home project, I received a rejection with no additional feedback. The least companies should be able to do is provide feedback when asking applicants to put in this amount of work.
