solved Task:Â KFC gave away free food and up to $50k

Task: 
KFC gave away free food and up to $50k with its mobile-based game – The Great Bucket Hunt (https://www.lifehacker.com.au/2021/06/kfc-bucket-hunt-game/), and they would like to obtain a good understanding of the players’ experience. KFC would like to conduct some marketing research, adopting a qualitative research method, i.e., interview. However, they are unsure if it is the best approach to gather useful information in this case compared with quantitative or mixed research methods. Please critique the proposed qualitative research method (i.e., interview) for KFC and based on your critique, provide ONE research design suggestion for KFC.
