Meta Data Science interview questions

First call with an interviewer and the following technical (SQL, PANDAS) and product sense rounds. They canceled the product sense after I failed the tech part. (but in 4 days which was super confusing, two hours before the interview). The tech part was pretty easy but I got confused with the questions and started to answer on the route of the problem and didn't write the code in the beginning and then ran out of time. Don't be me!

Confusing and difficult to grasp the environment/job details needed. Each step of the process did not get harder but the position became more and more vague as it went on.
