Qualifications and experience required

Whilst you may not be required to hold a degree, it can be beneficial during the application process and relevant degree subjects include statistics, mathematics or economics. Postgraduate degrees in data science are becoming increasingly common amongst graduates as they are helpful for developing important skills in analysis. Alternatively, there are a range of short courses offered by universities.

In terms of work experience, you may be at an advantage over other job applicants if you have gained experience through an internship, summer job or university placement year. This will help to not only demonstrate your interest in the industry, but also give you an insight into how companies work and allow you to build a useful network of contacts.

How to become a data analyst

To become a data analyst, you will be required to have a range of skills, including:

  • Analytical and problem-solving skills
  • Attention to detail
  • The ability to handle large amounts of information
  • IT skills
  • Familiarity with data analysis techniques

Along with these basic skills, you will need to have good working knowledge of data cleansing, modelling and enrichment techniques, as well as experience with analysis applications (as well as the fundamentals such as Microsoft Excel and Google Analytics). Whilst companies are likely to offer training within entry-level jobs, you should be familiar with software packages like Tableau or Power BI.

Within an interview you are likely to be asked questions that explore your ability to produce graphical representations and data visualisations, and your familiarity with industry-specific databases. An example of a question could be “what is data cleansing and what are the best ways to practice this?” or “what should a data analyst do with missing or suspected data?”. An employer may also want to know about the challenges you have faced within a previous role, as well as how you overcame them to complete your work. You should always use the STAR technique when answering interview questions, which you can find out more about here.
