What a terrible interview! an unprofessional tech interviewer dressing in a self-righteous manner, an unintelligible accent, kindergarten level questions. The first thing interviewer did is to let my give up and said goodbye to me since I am not unemployed right now. What a ridiculous logic! Do I have to resign before I can join Freelancer interview???
That is really the worst interview, a waste of time! I can't imagine working for such a company where people there at such a low level (even don't know how to allocate memory in Numpy and Python)...
Strongly discourage to apply for this firm unless you're really as low as some tech staff there.
