Was contated for a codility, and hyped up. They didn't follow up and when hired said they had to 'freeze hiring' which would be good to know before doing codility and waiting 2 weeks....
I would avoid considering 60% of the responses here are similar. They do not seem serious.
I applied online. The process took 2 weeks. I interviewed at Unified (New York, NY) in May 2015
Interview
first round with hiring manager and second with 2 other data scientist. Mostly about the background, resume and underlying keywords. Was positive experience till this part. Then i was given an open ended data assignment and hr just stopped emailing. Looked like position was filled, but weren't courteous to let oneself know. Very unprofessional.
