I have applied for the role online and after a week HR invited to the first screening call. Prior to that they send you personality test were you need to select adjectives around yourself. Call was held with two HR managers, questions mainly about company culture, expectations, learning, your contribution to the business, strengths, weaknesses. Within 2 days I was invited to the 2nd phone screen call with hiring manager. It took around 20-30 min, quick standard question session on experience and expectations. After this I've been invited to come to London office and have interview with the same hiring manager. Interview was rescheduled several times which was already very strange. Face2face meeting went well, standard questions on experience, expectations, strengths, weaknesses, pros and cons from previous company, why you want to join DataXu, etc. By the end of the meeting I was given positive feedback and they see me as part of their team as I can contribute with good experience, also I was told HR will reach me soon for the 4th final interview that sound very promising. I had followed up with thank you note showing my interest to join the company and the most odd thing happened. A week after I got generic automated rejection message without no feedback. I made one more follow up at least to find the reason and thank for the experience and they had never responded to me. I believe after 3 interviews you at least deserve to get feedback. I found it simply unprofessional and disrespectful.
