Forrester interview questions

Day 1, 30 minute interview with HR, Day 2, HR called at 9am and asked if I could find time to interview over the phone by 1pm, 30 minute phone interview with hiring manager, after interview HR asked me to come in the next day Day 3, 2 hour interview on site with 3 employees- all nice & familiar with the position and company (however, 2 with less than 2 yrs at the company), Day 6, received an email with a research project to present in 1 week, Days 7-Days 13, spent 40 hours analyzing data and creating a ppt. Day 14, presented 30 minutes on site to 7 employees (of which 4 were VP's and of the 7, 2 were over the phone). Upon completion of interview, HR rep said, you'll be hearing from us 'soon', and 'hopefully later today'. No word that day. (they set expectations here, but didn't follow through) Day 15- no communication Day 16- no communication Day 17 no communication- finally I sent an email follow up and didn't receive a response, if they were undecided, they could have at least responded that it was taking longer than expected, etc. Day 18, I called and HR told me another candidate was selected, I'm not sure if they were planning to f/u or not- had I not called. Overall, the process was time consuming and eventually disappointing. Project received was vague and data was lacking in it's ability to tell a statistically valid story (also contained errors and transpositions). Data file had 384 variables for me to 'play with' to find research results- so I spent more than 40 hours with the file, in hindsight, I put in far too much effort, but based on the interviews and process, it seemed promising. It was challenging to present skills and a finished/polished presentation with results at a simplified level. Also, they wanted me to demonstrated advanced statistical methods, but when I presented- the people in the room had no understanding of these methods- or more like a superficial understanding. They wanted me to demonstrate abilities and competency with advanced statistically techniques but present at a simplified level- still showing my capabilities. They should have been clear up front- that the majority of people viewing the presentation wouldn't understand the more complicated statistics, since they were asking me to showcase analytical abilities for an analyst position. No background information or detailed questions (customer X has these issues or questions) or methodology were provided for the exercise, just a survey instrument. Also, some of the computed variables were created with 'proprietary' (unknown) formulas and it was unclear whether or not weighting was used, it at all. They also expected the ppt to follow their template with branding and color/style guide, etc. The process felt straightforward and was positive, those I interacted with were all nice as well as smart and appeared quite competent in their roles. They communicated clearly and often and then appeared to give up after I put in a significant amount of effort. Also, I'm not sure they understood what they were asking of me, paperwork said, "there is no right answer", but clearly there was a wrong answer.
