Introduction
Moving from studying in a class to moving within the professional industry is an essential step for aspiring data scientists. While students may learn Python, statistics, SQL, machine learning, and data visualisation, a Data Science Internship Experience can enable students to apply their skills and knowledge to a real-world business setting. By participating in a Data Science Internship Experience, students can work with practical datasets, industry tools, professional practices, and skilled professionals. As such, students can develop technical and communication competencies, meet employer’s expectations, improve weaknesses, and obtain valuable work exposure to support their future career in data science.
Understanding the Transition From Classroom to Industry
Classroom education helps lay the foundation for a career in data science. Students generally learn the concepts through assignments, lecture notes, exercises, and academic projects. However, the professional experience is often different.
Real-world data sets are often messy, and business problems can also be ambiguous.
Data science internships help students understand how academic knowledge can be practical. A few of the main differences include:
Classroom projects often have clear requirements.
Industry projects may require students to first understand the problem.
Academic data sets are often ready-to-use.
Real-world data sets can be dirty.
Deadlines in classrooms are sometimes flexible.
Professional projects have specific timelines.
Real-world projects require multiple teams to cooperate.
This transition helps students understand the intricacies of a data scientist’s job. Thus, an internship is an invaluable experience to understand that practical data science is not just about writing codes.
Working With Real-World Data
One of the main reasons why students pursue an internship in data science is to work on real-world data sets. Data Science Internship Experience These data sets are often generated from the following:
Websites
Apps
Customer and business data
Surveys
Transactions
Other sources
This data may need to be cleaned and prepared for analysis prior to generating meaningful insight. Interns may be required to perform any of the following data preparation tasks:
Collecting datasets
Checking quality of datasets
Looking out for missing values
Removing duplicates
Addressing inconsistencies
Data type conversion
Dataset combination
Preparing datasets for analysis
Working with real-world data sets teaches students the extent to which data may need to be prepared and cleaned prior to generating meaningful insight. For instance, one may have worked with a small and well-prepared dataset in the classroom. However, one may encounter thousands of records that contain missing, incorrect, or inconsistent values in an internship. Thus, a Data Science Internship Experience can help students overcome such practical challenges.
Applying Python, SQL, and Data Science Tools
Technical expertise is critical for data scientists, and a Data Science Internship Experience can help students apply Python, SQL, and data science expertise to analyse datasets. For instance, Python is useful for data analysis, automation, visualisation, and machine learning. Libraries such as Pandas and NumPy can assist with data manipulation, while visualisation libraries such as Matplotlib can help present analytical findings.
SQL is useful for data extraction from SQL databases. One may also be required to group and aggregate information retrieved from databases using SQL queries.
A Data Science Internship Experience can provide students with practical application of the following data science tools and technologies:
Python
SQL
Pandas
NumPy
Matplotlib
Scikit-learn
Jupyter Notebook
Power BI or other visualisation tools
Excel
Cloud-based technologies
And other relevant tools
Thus, a data science internship can help students develop technical expertise with the tools and technologies used in the industry.
Learning Exploratory Data Analysis and Machine Learning
Exploratory Data Analysis (EDA) is another crucial aspect of a data science career. Prior to developing a machine learning model, data analysts and scientists often engage in EDA to evaluate and understand a data set. During a Data Science Internship Experience, students may be required to:
Analyse data distributions
Identify outliers
Examine relationships between variables
Find correlations
Create visualisations
Compare categories
Identify trends
Investigate anomalies
And other EDA-related activities
Some internships may also provide students with an opportunity to gain experience with machine learning. Data Science Internship Experience The extent and depth of machine learning may differ depending on the project requirements. Some of the topics include classification, regression, clustering, and other relevant topics.
However, a crucial lesson in machine learning is that it is not about selecting the best algorithm, but about understanding the following:
Data quality
Feature selection
Model training
Overfitting
Model evaluation
And other relevant aspects
A Data Science Internship Experience can help students understand these crucial machine learning concepts.
Understanding Business Problems and Finding Solutions
A major difference between academic projects and professional projects is that professional projects often involve meeting specific business requirements.Data Science Internship Experience While one may be provided with a specific question such as ‘predict X’, in the industry, questions are often less specific. For instance, businesses may seek to understand:
Which products generate the most revenue?
What influences customer behaviour?
Where are inefficiencies in business processes?
Which customers exhibit similar characteristics?
How can organisations improve decision-making?
What trends can be identified?
And other similar questions
A Data Science Internship Experience can help students understand how data science can drive business insights. For instance, an intern may be provided with a problem statement and required to complete the following:
Conduct an exploratory data analysis to better understand the problem.
Determine the most relevant data to answer the question.
Clean, prepare, and analyse the data.
Present analytical insights that can help the business.
Thus, students can learn how to align their analytical skills to help solve business problems.
A technically complex analysis may not be sufficient if the business is looking for solutions to specific issues. Therefore, identifying the actual need is critical prior to developing solutions.
Developing Communication, Teamwork, and Professional Skills
Data science is not a solo endeavour. Data scientists often collaborate with analysts, developers, managers, business teams, and other professionals. A Data Science Internship Experience can offer students the following professional soft skills:
Communication
Teamwork
Presentation
Problem solving
Time management
Documentation
Professional writing
Collaboration
Adaptability
And other relevant skills
Communication skills are particularly crucial for data scientists. Many professionals are not familiar with the statistical and technical aspects of data science.Data Science Internship Experience Therefore, an intern may be required to translate technical analysis into business insights that stakeholders can understand and act upon.
In addition, interns can gain insight into how professional meetings are conducted, how to give and receive feedback, and how projects are managed and documented.
Challenges and Lessons From a Data Science Internship
A Data Science Internship Experience may come with several challenges, many of which can be difficult to overcome for the first time. Some of the major challenges include:
Unfamiliarity with new datasets
Understanding business requirements
Using new software
Code debugging
Meeting deadlines
Presenting findings
