LinkedIn Data Scientist interview questions

I had 3 phone interviews with Linkedin data scientists. Everyone I spoke to was very bright, thoughtful and polite and made a great impression. On the first two calls I was asked how I would solve some of the problems Linkedin worked on (ex: people you may know) and on the third call I had a more technical coding interview. However I didn't have a machine learning background at the time, so they did not give me an offer but encouraged me to e-apply after I had taken some of the machine learning classes I was planning to take the next semester. Considering how little machine learning I knew at the time it's a wonder they even gave me a first interview, let alone 3.

There should be two rounds of phone interviews and one on-site interview. I applied for the position in LinkedIn career page. A recruiter contacted me the next day and scheduled my first phone screen. After the first phone screen, the recruiter contacted me regarding the next round of the phone screen.
