I applied through a recruitment agency. Had an initial phone interview with one of the managers, following which I was asked to complete their assignment and present it in front of the team. I was sent the assignment on Monday evening and asked to come in to their office to present it on Friday (tight deadline for someone who's employed full time). The assignment was based on analysing a dataset and deriving as many insights from it as possible. The general impression they gave in the instructions was that they're flexible when it comes to the form of the output and it was stated that one should not spend more than 2 hours putting the results together. Unfortunately, I had to postpone the interview on Friday, as I had to stay longer at work. I tried to reschedule the interview, but they instead asked me to send them the file with my results (which was meant to help me deliver the presentation rather than serve as standalone piece upon which I would be judged). They never confirmed the new date for the interview, but instead sent me an email saying that they decided to not progress with the interview. The main reasons they gave was that colours in my presentation were not consistent, and not "colour-blind friendly". They also made comments on a couple of charts I prepared claiming they don't make sense to them. Well, maybe if you had given me a chance to come in and explain my results to you, they would have. The move was extremely unprofessional and unfair - the whole feedback was focused on incredibly minor details of the visual part my presentation and no comment at all was made on the actual content of it (i.e. my findings). The instructions were also misleading, as they implied the presentation is not expected to be immaculate. Overall, a very unpleasant and disheartening experience given the amount of time and effort put into this.
