Me postulé a través de un reclutador. Acudí a una entrevista en LinkedIn (Sunnyvale, CA) en abr 2019
Entrevista
A recruiter reached out to me on LinkedIn(!) regarding DS roles. I spoke to him on the phone - standard HR round, finding best fit. I was told there will be two more phone screens - one SQL coding + another case study based. If I cleared them, next step is on-site. I spoke to one of the hiring managers in the DS team for the first coding exercise. A brief mutual intro and she said she will ask one or two SQL queries depending on time. 45 minutes was set for this. She started with a SQL question regarding LI page views data - how to gather info regarding activity of crawlers (probably not the right name, but I forget what she exactly used). I started writing the code and took almost all remaining time, but I could sense she wasn't happy with my answer. Not surprisingly, I never heard back from them :)

There is a table of page view data. Two columns: Member ID and time stamp. You can assume this is for a 24 hour period. Members vs. guests/visitors are differentiable via ID's. Have to come up with a method for determining which all activities are crawler related (and not my members) and write a query for the same as well.

It was quick, efficient, and not too challenging. I was asked 8 questions and the interview was more of a dialogue. It felt more like a conversation. I enjoyed it and would recommend applying to LinkedIn.
