Kepler Communications interview questions

I interviewed for a job opportunity at this company which ultimately proved to be a role that was never genuinely open. It seemed like their human resources team had no intention to hire and was conducting the multiple rounds of interviews just to toy with me and to test my boundaries. I felt they were extremely manipulative with zero ethics and horrible workplace culture which reflected in their behaviour. They had no respect for my time and their human resources team behaved as though they could absolutely get away with any sort of foul behaviour as I am just another candidate.
