Ho presentato la mia candidatura online. La procedura ha richiesto 3 settimane. Ho sostenuto un colloquio presso X (San Francisco, CA) nel mese di ott 2013
Colloquio
I applied online via the website. I was contacted promptly for a HR phone screen. This screen included basic personality tests. I then had two technical phone screens, both of which included collaborative coding, probability questions and algorithmic problems. I was invited onsite for the final set of interviews. I met with five data scientist and one data manager. All of them asked whiteboard coding / ML theory / algorithms questions. I received little information regarding the work life at Twitter.
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
