I applied online. The process took 2 weeks. I interviewed at X (Singapore) in Mar 2016
Interview
A phone interview will be arranged via email, the interview will take about 30min - 1h. They didn't even bother to get back with the results. The interviewer was very unprofessional in my opinion - she did not bother to learn more about the candidate, but instead of purely focused on technical questions and sounded very monotonous as if she was reading off a script. This was no doubt one of the worst interviews I have had.
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
