1. Simple data analysis question 2. Invited to an onsite info session. This session took 1 hour besides commute. This info session is really time consuming and unnecessary for onsite. I guess the only reason they do so is to save time and budget for the HR people. They asked all candidates to join so they only needed to do it once rather than explaining their company multiple times. 3. A more complicated data analysis assignment to be finished in 1 week. No specific requirements but was told to tell interesting stories found in the assignment. Got rejected after submission and was told "my estimate is not accurate enough". So they were expecting a certain result but gave no clue in advance. There are certain other companies offering the similar positions and assign take-home projects. Yipitdata is among the worst as others tell you what they expect in your analysis.
