I applied online. The process took 4 weeks. I interviewed at X (Boston, MA) in Sept 2017
Interview
I applied online. The process took about a month. 2 phone interviews with HR managers, test and personal interview with team members (It took about 3 hours). Free lunch was served and people were friendly.
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
