Cisco Data Scientist interview questions

Applied online in December 2016. The recruiter contacted me after a week and set up a 45 minutes screening. She said it includes programming and system design. In the screening I only got a question on cloning a graph which is in my opinion is more appropriate for software engineering role than a data science role. Apparently, since Cisco is a network company, proficiency in graphs is very important to any role. However, this was not mentioned in the job description which made me mistakenly apply for the position.

Received email to schedule the interview. The following week I interviewed with three different people via WebEx. The next day I received an email from the hiring manager with data files attached and was asked to complete a "homework" assignment within the next week. Everyone was very nice and easy to talk to.
