Machine Learning Techniques
The various machine learning algorithms a data scientist should be familiar with, viz., data regression, classification, clustering, etc., are evaluated in this test. It poses queries on how to select an accurate ML technique that can be used for the given dataset and how to use the ML technique to achieve the desired functionality in machine learning models.
Data Visualization
Data Visualization is a crucial skill covered in Data Scientist training as it allows professionals to effectively communicate complex data and insights to various stakeholders. By creating visually appealing and easy-to-understand charts, graphs, and dashboards, data scientists can help decision-makers quickly grasp key findings and trends, leading to more informed and data-driven decision-making processes. Additionally, data visualization plays a key role in identifying patterns, outliers, and correlations within datasets, ultimately helping organizations optimize their operations and drive business growth.
Statistical Modeling
The individual’s ability to build different types of statistical models, viz. parametric, nonparametric, and semiparametric, to gather, organize, analyze, interpret, and statistically, design data are evaluated in this test.
Tensorflow
TensorFlow is an end-to-end machine learning platform used to build, train, and maintain ML models. The test takers are gauged on their skill in working with TensorFlow’s standard datasets, data pipelines, preprocessing layers, and other tools.
Deep Dive into Machine Learning Models
The assessment also evaluates the candidate’s deeper level of knowledge on machine learning models such as supervised, unsupervised, and reinforcement learning and their algorithms like Linear Regression, Logistic Regression, Decision Tree, etc.
Use of the Data Scientist - Intermediate Test
The Data Scientist Test for hiring data scientists is of intermediate difficulty and assesses advanced concepts like Machine Learning Techniques, Data Visualization, and Statistical Modelling.
This assessment can be used to recruit mid-level data scientists and test their intermediate-level skills to perform data science operations. It evaluates their ability to work with data and their knowledge of machine learning & its techniques, statistical analysis of the data, and neural networks. The candidate’s skill to automate data, build machine learning models, track the models, and monitor & retrain models using TensorFlow can also be analyzed using this test.
The Data Scientist test helps assess individuals with a few years of hands-on experience working with data. It can help narrow down data scientists who have the capacity to create machine-learning-based tools with extensive knowledge of operations such as data extraction and mining, data cleaning, using data classification & regression algorithms, performing data wrangling, conducting advanced analytics, and leveraging deep-level machine learning techniques to deliver valuable business-focused insights.
For hiring to fill job roles like Data Scientists, Data Analysts, and Data Engineers, which require a few years of experience in the field, the Data Science (Intermediate) Assessment can be used. Candidates who score well on this test will possess adequate skills to work closely with the business and use data to achieve the company’s objectives of increasing operational efficiency, identifying new business opportunities, and improving marketing and sales programs.
