A day is enjoyable when I can continue with my own work and solve problems for the team and myself so that we obtain a good result. Then you get a lot done and that gives me a good feeling.

A day is less enjoyable when I have a lot of meetings and questions in between. Then I can concentrate less on my own work

Firsthand experience

A client asks you to predict the company’s turnover? What do you do?

First, you ask the client for old data. You have it checked by someone from your data team, to see if it is unique and clean data. You get this data back and on the basis of this see if you can build a model that can predict the turnover. It could be that you don’t have enough data, then you discuss this with a junior in the data team and they ensure you do have sufficient data. When you have completed the model, you can show the client what your findings and the predictions for the company’s turnover are.
