Interviewers will ask this question for several reasons. The first is to determine if you are familiar with each step used in the data analysis process. The second is to determine which of these you favor. This may indicate that the data analytics team delegates specific processes to individual members of the team based on their aptitude, skills, and preferences.

"If I had to select one step as a favorite, it would be analyzing the data. I enjoy developing a variety of hypotheses and searching for evidence to support or refute them. Sometimes, while following my analytical plan, I have stumbled upon interesting and unexpected learnings from the data. I believe there is always something to be learned from the data, whether big or small, that will help me in future analytical projects."

It is acceptable to prefer completing one task over another. However, in many cases, you would be expected to have experience performing all these types of tasks. Avoid showing aversion to any of the steps in the process when indicating which step you enjoy performing the most, including explaining why it's your favorite. This will illustrate your strengths to the interviewer.

As a data analyst, I always pay extra attention and time while I perform data cleaning and data preparation because it is the basis on which a successful and fruitful analysis can happen. As it is said, "Good data, good result. Garbage data, garbage result." Having said that, I enjoy the data visualization and presentation part because it tells the story hidden in the data and what we worked for.
