Why Data Science Internship?
Before applying to any Data Science Internship, the first question that should arise in your mind should be why Data Science Internship.
First of all, Data science internships don’t happen overnight, and they are not a cup of tea, though. They need time and effort. There are many things you need to work on before you can start applying to become a data science intern, that we will discuss in this article late on.
Internships are a great way to get your foot in the door at the company you want to work for.
Especially if you’re going to land a data science internship. There are plenty of benefits for data science interns. They get the opportunity to learn from professionals, gain practical experience in their field, and they can build a robust professional network.
Currently, data science is a really popular area to work in. Searches for the term “Data Scientist” have increased by 6 times in 5 years. At the moment data science is ranked as the sixth-best job on Glassdoor, namely because of its high rate of pay, career opportunities and availability of job openings.
Data science is quickly becoming a vital skill as more companies scramble to capitalize on the hordes of data they can collect on clients and customers.
Naturally, as the demand for data scientists grows, more students want to break into the field, which means they’ll be looking for internships.
In fact, a recent McKinsey report study on big data found that demand for deep analytical talent in the United States & India could be 50 to 60 percent greater than its projected supply by 2019.”
What is Data Science?
“Data Science is the concept of collecting, storing and analyzing data (structured or unstructured) for extracting useful insights from it.”
The amount of data being generated every day is increasing exponentially! The sources of data and the ability to collect and store it has come a long way in the last decade. Companies are using a variety of tools and techniques to mine patterns in the data and gather useful insights. That, in a nutshell, is what data science is all about.
A lot of people think that to be a good data scientist, they just need to have good coding skills and understand machine learning statistical concepts. But what they lack—and what we look out for—are problem-solving skills and business acumen.
How to Start Data Science Journey
For a starting position in Data Science, as an intern, you should at least have your basic statistics and programming concepts cleared.
Technical Skills for Data Science Internship
Some of the general technical knowledge you need:
- Basic knowledge of either Python or R. Whether you have more of a computer science background or statistics background, you need to have the basics down of either language.
- You should know the basics of SQL or any other database in order to retrieve data from a database. It is not very hard to learn and you can have the basics down within a weekend. You should also familiarize yourself with git.
- Familiarize yourself with the Linux environment.
- Makes sure your stats background is rock solid. If you’re majoring in economics, you’ll probably have completed some math coursework that dived into statistics/modelling. Review those notes if you can to help you refresh your memory, it will synergize well with everything.
- Hadoop, Scala and Spark are useful technologies to learn in relation to Big Data, though not necessarily essential. It would also be good to have a working knowledge of Cloud Computing.
- I think you are good to go with only 2–3 undergraduate courses in statistics and 2–3 courses in computer science. Know basic probability theory, what confidence intervals, t-tests, and p-values are. Understand what bias is and how easily it can be introduced in the data you are analysing. Know statistical learning methods such as linear regression, logistic regression and one or two more classification techniques. Also, understand the basics of computing. How to name variables, functions etc. Know how to construct a basic for loop and if-else statements.
Soft Skills companies look for when hiring data science interns
If you want to become a fully-fledged Data Science intern you should also focus on Soft Skills. Some of the common Soft Skills are mentioned below:
- Indirect experience: If you don’t have any work experience, start volunteering or working in your community (ex. cashier, database handling). Before your data science interview, be sure to take time to think about what skills you have gained working at past jobs and how you can best apply these to your data science internship.
- Attitude: Companies want someone who is willing to go above and beyond the call of duty and someone who is adaptable to different situations. In addition always keep in mind that one of the main goals of an internship, for a company, is to test out potential candidates for full-time positions.
- Structured Thinking: Having a structure not only helps an analyst understand the problem at a macro level, but it also helps by identifying areas which require deeper understanding.
- Networking: Take part in Events taking place outside your university will have a mixed crowd where students, young professionals and managers will be in attendance. You never know when someone you meet might think you are the right fit for their company and put in a word that gets you at the top of that pile of resumes.
- Culture: Every new employee in a company adds a bit to the company culture. It’s important that you understand the company’s culture and it fits how you work. However, always keep in mind that asking your interviewer these questions is extremely important, as an interview involves a mutual decision.
Building Your Online Brand
What makes a good data science portfolio?
Building a digital portfolio takes time and effort. To build one, you need to:
- Identify your knowledge, skills, and abilities (what do you know? What can you do?)
- Similarly Gather evidence (how can you demonstrate your knowledge, skills, and abilities?)
- Above all organize and assemble your portfolio (how can you categorize the evidence you have gathered?)
In conclusion, a digital portfolio or brand is a collection of files (projects, documents, photos, videos, etc.) that you can use to reflect on your experiences and demonstrate your skills and accomplishments to potential employers, investors or customers.
A digital portfolio is a popular alternative to a traditional, paper-based portfolio because of it:
- Is easy and quick to update
- Can support multimedia file formats
- Is easy to share with people, even if they are not nearby
- Can be less expensive than paying for portfolio cases, paper, printing and photocopying
- Saves paper and is environmentally friendly
It takes time and effort to develop a digital portfolio. However, the process of developing and updating it will help you reflect on what you have accomplished and determine what you would like to do in the future.
Therefore a strong portfolio can help you to review and evaluate past experiences and learning, and present your knowledge, skills and accomplishments in a compelling, visual manner.
Work on Projects
We believe the best way to learn anything is by putting your knowledge into practice. Nothing says “I know this technique” like showcasing it in a project. In other words, building an end-to-end project gives you an idea about the different possibilities and challenges a data scientist potentially faces in a day-to-day role.
Building your Github Repository
Anything which shows your project code or programming skills is what Data Science internship recruiters most preferably look for. GitHub/Bitbucket/other or your own VCS/SVN is the place where you host your code. This is a convenient way to show all your code. You should also start building your GitHub profile at an early stage. This is essentially your data science resume which anyone in the world can access. Anything which shows your project code or programming skills is what Data Science internship recruiters most preferably look for.
Mistakes while learning for Data Science Internship/Job
Spending too much time on theory.
Many beginners fall into the trap of spending too much time on theory. Whether it is math-related (linear algebra, statistics, etc.) or machine learning related (algorithms, derivations, etc.).
Coding too many algorithms from scratch.
This next mistake also causes students to miss the forest for the trees. At the start, you really don’t need to code every algorithm from scratch.
While it’s nice to implement a few just for learning purposes, the reality is that algorithms are becoming commodities. Thanks to mature machine learning libraries and cloud-based solutions, most practitioners actually never code algorithms from scratch.
Having too much technical jargon in your Data Science resume.
The biggest mistake many applicants make when writing their resume is suffocating it with technical jargon.
Instead, your resume should paint a picture and your bullet points should tell a story. Your resume should advocate the impact you could bring to an organization, especially if you’re applying for entry-level positions.
Overestimating the value of academic degrees.
Sometimes, graduates can overestimate the value of their education. While a strong degree in a related field can definitely boost your chances. It’s neither sufficient nor is it usually the most important factor.
Neglecting communication skills.
Currently, in most organizations, data science teams are still very small compared to developer teams or analyst teams. So while an entry-level software engineer will often be managed a senior engineer, data scientists tend to work in more cross-functional settings.
