OpenTable interview questions

I initially applied mid May and the initial HR interview was a week later. Having been moved forward it was a further week before I had an interview confirmed that was on the Bank holiday Monday with 3 people in the same role. I passed this interview and was informed I would have a 3rd and final interview with senior management. During this interview I was told that I was up against an internal candidate which was fine with me. The next day I get an email with an invite to another interview with even more senior management. I was confused as I was told the 3rd round was the final one. During the 4th interview I was asked almost identical questions to the 3rd and assumed this was the final step of the process. Alas this was not the case. A few days later I am sent an assignment with a bulk of data to analyse and create a dashboard, 30-60-90 day plan and a weighted scorecard. I had a catch up with the initial HR person where I was informed that I was the only person that had made it to the 'final' 3rd interview and that the senior manager had in fact fabricated the internal candidate. I decided to start cleaning the data but after spending time doing it I made the decision to give up as it felt as if I had already wasted enough time (6 weeks) and several hours of interviews. I would recommend that you are clear from the outset not only to the potential recruit but also align internally on what the process is and the timeline.

Had an initial call with member of the team. Very quickly get an email from the recruiter asking me to provide availability for next round interview which I did. 2 days later having heard nothing back I receive an automated email telling me that the role had been filled. Hugely unimpressive candidate experience
