Entrevista
How recruiters interact with you tell a great deal about the culture of the company, and because of the unprofessional behaviors of a recruiter I didn't even apply in the end. A recruiter from Twitter reached out to me for an introductory chat for 15 mins. They cancelled in the last minute to reschedule, which can happen. When trying to reschedule, their tone was impolite and demanding which led me to not want to even have the 15 min chat with them. I emailed and canceled politely. They didn't even have the courtesy to respond, and then I knew I made the right choice not wasting my time. Just imagine how the rest of the interviews would go (or even the work life in Twitter would be) when their recruiter who reaches out to you treats you like you owe them something. Data scientists have a lot of options to choose from, and Twitter showed they are not a good one even before speaking with them.
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
