First is a 9-step pseudo code, but I think that is not a coding test, but a math test! The interviewer just asked you why they are doing this step, what does this or that formula mean. Second, very stupid! Just show you the entire process of their their marketing and asked you how to generate a metrics of how to evaluate their marketing performance. Then followed by a math test. Unfortunately, the interviewer didn't make himself clear, when you asked, he just thought you were asking for clue?! Third one is a general behavioral test. No coding at all. Just describe your most recent project.
