Chances of someone finding your portfolio is through your resume. Hiring managers go through your resumes very quickly, and you have just a few minutes to make an impression.

1. Appropriate Length

Although it depends on the work you have done, try to keep it simple. There should be enough space to include all your work in 2-3 pages. Try not to include objectives and conclusions, keep space for your skills, projects, and experiences.

2. Relevant Coursework

It is the work that is performed by trainees for the purpose of learning. List out all the relevant coursework that you think will be applicable to the job description.

3. Technical Skills

List all the technical skills of yours that the job profile mentions. The skills you are best at should be written at the start and the skills that you have but are not the best at should line up afterward.

Remember, to ALWAYS rate yourself on your skills. Words such as proficient and familiar must be used to give ratings, don’t give yourself numerical ratings.

4. Work Experience

It’s best if you have any experience, but what if you don’t? You have projects, thesis, competitions, and internships that you can include. These are substitutes for work experience if you are a fresher to put into your portfolio.

5. Related Internships

There are many data science-related internships including data analyst, data engineers, business intelligence or analyst, research engineer, and others, not just data scientists. The internship should provide you relevant work and you should learn something from it.

Some form of data collection, analysis, model building, or visualization is preferred for an actual job.

But why internships? Most importantly because companies want to hire people who can start to work on real stuff with minimum training as it is time-consuming and time is money in the corporate world.

“Don’t just blabber, show it”. Having internships shows that you are serious and passionate about work and are not another candidate who says, “I am very passionate about data science and want to learn more about it”.

6. Real-world Projects

Projects give you an opportunity to get experience when you cannot get it from internships. Generally speaking, 3 data science projects are enough to cover the common job responsibilities for job profiles you are interested in. Always, write up your projects in a structured manner.
