Hanover Research Research Analyst - Survey Design interview questions

I applied for Market Research, but got an email from HR, suggesting to look into another role( Survey design). First round is an online assessment to be done for about 55min. they are more of personality questions, odd man out etc. After 2 weeks, I interviewed with HR for 30 minutes and at the end of the call, she told me that, they are happy to move for next round, which is Survey Assessment. It has data from survey and corresponding questions that need to be addressed. However the questions are clear, the wrting part or answers part as to what they are looking in it is unclear ( More on analyis or more on looking for poilished client presenatations) . I worked on it for 8hours over 4 days and sent them the assessement. I got reject after a week mentioning that, they are looking for some one with more client side presenation and wirting related experience. I felt bad as , I have spent more time on analysis, than polishing it. The overall process took exactly 1 month and felt that, I was robbed of my time as my resuem speaks of my rleated experience, which they have shown as concern for rejection
