Data Scientist Skills Assessment

Assessment Details
Assessment Summary
A Data Scientist is a highly trained individual who is mostly technical but also able to interrupt data in a business manner. Data Scientists are required to interpret a lot of complex data. To do this, they employ techniques like machine learning, algorithms, and various types of modeling to identify patterns in the data. Once they have identified patterns in both structured and unstructured data sets, they are required to act on such data in ways that help the business. This assessment contains 10 questions that are designed to test the varying skills of the candidate’s ability to succeed and thrive in the role from a variety of different skills that are relevant.
Skills tested in this assessment
Data Scientists must be great communicators with a high level of programming expertise. They must have strong skills in manipulating and interpreting data. Data scientists need to be proactive and good learners, so they can stay on top of evolving technologies. Specifically, in the Vervoe skill assessment, the following skills are looked at it in detail, python coding ability, machine learning, the skill level of using TensorFlow, and their communication skills.
What to test with this assessment
From a carefully constructed set of questions that test an important subset of the required skills to successfully be a Data Scientist, you will be able to determine their abilities in solving theoretical machine learning problems along with practical coding problems that occur in TensorFlow and in Python. Furthermore, you will be able to see communication skills as this is an important skill in the role.

About the Data Scientist Skills Assessment

Want to hire the best Data Scientist to grow your business? Use our expert Data Scientist skills test to hire the best person and never make another bad hire.

Data scientists turn large sets of raw data and feed it through algorithms that they’ve developed to derive insights in the forms of patterns or trends, so that they’re able to pass these along to executes for implementation within a business.

Candidates who perform well on this Data Scientist skills assessment will have all the technical skills to run machine learning algorithms to analyse data to retrieve meaningful information which can be used to help a business. They will also have the soft skills to communicating their findings to executives of an organisation.

You can expect to learn whether a candidate knows how to prepare a data set to be suitable to be fed into a machine learning algorithm, identifying the dimensionality of a data set, knowledge and practical application of python and their knowledge of using TensorFlow to partake in machine learning activities.

You will need to find a candidate with strong skills in python as this is an extremely beneficial skill for data scientists. Python enables a high level of manipulation of data through code packages that are able to the public and allow data scientists to analyze large data sets.
Machine learning has become a very important skill to look for in a data scientist because they will be required to analyze large pieces of data. Machine learning allows the computer to learn to identify patterns which the data scientist deems important and that will add value to your business in a semi-automated fashion.
You should query the data scientist’s proficiency in TensorFlow as it is one of the main open-source libraries in which you can train machine learning models. When questioning a candidate, understand where they have applied TensorFlow, previously focusing on the scale of data and the outcomes that we’re able to be derived.
Data scientists must be good communicators, this is due to the fact that whilst they may be technically gifted if they’re not able to communicate what they’ve done and the outcome they were able to achieve their work will be useless. The research and outcomes that a data scientist performs will be highly valuable and a strategic move for the business when it is able to be communicated correctly to the relevant stakeholders.
