Me postulé en línea. El proceso tomó 1 semana. Acudí a una entrevista en X (San Francisco, CA) en ene 2019
Entrevista
Was quickly contacted to set up an interview after applying (first company out of ~20). Meeting was set with senior data science team member. We discussed four areas, my background, the role, and worked through a specific example of work to be completed, and follow up questions.

Pregunta 1
Was asked to discuss a KPI to measure new active users and retention, asked about pros and cons of approach.
The recruiter got in touch to set up a screening call. I was asked basic questions concerning my background and my motivation. Then we had a coding challenge with a question I later found on LeetCode under the Twitter section for the last 6 months.
Case study was interesting; interviewer was previously from uber so some similar interview questions, techniques do apply, overall a good engaging exercise. Nothing to complain about. Overall it is okay
