- Communication and Reporting
Through a series of questions on a range of topics, we are able to establish that this individual has the basic knowledge required for a data scientist role. We make use of adaptive testing approaches to understand to a high degree of confidence the skill level of individuals who take the assessments.
Our coding challenges are free form, where candidates are presented with certain data but it is up to them to come up with an appropriate solution. The goal of this task is to demonstrate that the individual has the ability to perform the tasks required of them as a data scientist without being guided towards the appropriate solution.
Case study submission
The final stage of the certification required the individual to complete a case study. This stage of the certification is graded manually and stringently by our data scientist experts.
The case study is split into two parts:
1. Technical report:
In the case of the technical report, the audience is a data science manager. It can be considered that the work is being presented to show how the task has been approached, why certain actions were taken, and how the work helps to solve the problem defined. There is no one right answer.
2. Non-technical presentation
The final stage was to adapt the information towards a non-technical audience. It is a common requirement for data scientists to have to present their work to others who have no background in data science. These audiences are interested in why the work was done and what the outcome was, typically not how it was done.
