DAC Senior Client Manager interview questions

2 stage interview process. Initial phone call which was really positive which followed by a face to face interview with presentation. Only had 36 hours to turn the presentation around and travel from Manchester to London to present which was all well and fine. The interviewer was insistent on having the presentation emailed over with any further questions I may of had, I was fine with that, what I wasn't fine was the lack of communication after the interview. Feedback was limited and the questions I emailed over had no replies. With this in mind I have to question whether or not there was a job on offer in the first place and the task was just merely a crude information grab.
