I applied through a recruiter. The process took 1+ week. I interviewed at X in Sept 2016
Interview
I was supposed to have a 45 minute technical coding screen but the guy was booked too tightly and only had 20 minutes (told me this at the beginning of the call). So instead of a technical coding screen it turned into a series of random business case style interview questions. Overall a pretty terrible - no wonder Twitter is plummeting as a company
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
