Computer Science Internships

What is a computer science internship?

As an intern, you’ll join a tech team (usually between four weeks and six months) where you’ll work on real projects and build the skills and experience employers need. Most computer science internships run during the summer months inbetween your second and third year of university.

You’ll usually work on a specific team, whether that’s on web development, mobile apps, data systems, cloud infrastructure or machine learning. Some longer internships might allow you to work on different aspects of computer science.

Internships are great because they allow you to take everything you’ve learned in the lecture hall and apply it in real life. It’s your chance to learn and develop your practical skills.

What will you actually do during an internship?

Your tasks and responsibilities will vary massively depending on which path you’ve taken and where you work. Here’s a quick breakdown of what you could be getting up to.

• Software engineering. You’ll write and review code and work on system design. Click to read our guide to software internships

• Data science and machine learning. Working with tools like Python, SQL and machine learning frameworks to build data pipelines and develop ML models for things like computer vision or fraud detection.

• Cyber security. You’ll focus on security testing, threat analysis and create security processes to protect company and customer data.

• DevOps/Site Reliability. You’ll use automated systems and make sure apps run smoothly using programmes like Docker and Kubernetes. 

Outside of these, you'll attend team meetings, get mentored by senior engineers, go to networking events and join workshops and training that’ll develop your career.

What skills do I need?

Internships are all about learning, so don’t worry too much about not knowing everything - employers expect that. It does help to have some knowledge about certain systems and programmes, as it can help you stand out during your interview. Employers will also look for candidates studying certain technical degrees, so they’ll be aware of what you already know,

Some technical skills you could work on include:

• Basic understanding of programming languages like Python, Java, or C++

• Knowledge of databases and using structured query language (SQL)

• Understanding of algorithms.

Outside of that, you’ll need to have a whole bunch of soft skills (which you’ll already have). These include:

• Analytical skills

• Problem-solving

• Attention to detail

• Teamwork

• Time management.

Ever dreamed of becoming a software engineer? Here’s how one intern felt about their time at NatWest:

It was a fantastic experience. I gained so much knowledge of working in a large organisation, how corporate life works and in general about banking/finance in software engineering. Would strongly recommend to anyone else. Software Engineer, NatWest

How much do you get paid?

How much you earn depends hugely on your employer. For example, jobs in central London will pay a lot more than jobs outside the capital. On average, computer science interns earn between £22,000 and £30,000 pro rata.

There’s so much potential to earn more, too. Once you become fully qualified, you could start at £30,000 per year and earn as much as £80,000 per year if you reach senior and managerial positions.

Is it difficult to get a computer science internship?

With an average of 101 applications per internship, they can be super competitive. Big-name companies can receive a lot more.

But don’t let that discourage you. There are opportunities everywhere. Computer science workers are in demand, and with generative AI booming, employers are looking for talented people to join them. Here’s how to improve your chances:

• Apply early and apply everywhere that’s relevant to you

• Tailor each application 

• Look beyond huge names; working for a small-to-medium-sized company can be just as beneficial

• Talk to your uni careers officer. You never know what you might have missed

• Upskill yourself with coding tests.

How do I get a computer science internship?

Most employers start recruiting their summer interns in the autumn. So it’s best to get your applications in before December.

You’ll begin with an online application where you’ll attach your CV and cover letter. You could also complete a coding assessment. If you’re successful, you’ll move on to the assessment centre and interview stage. You’ll take part in psychometric and coding tests as well as your final interview.

Remember, employers aren’t looking for perfection. An internship is usually a student’s first foot in the corporate door, so you’re there to learn. When applying, show recruiters that you have a genuine interest in the role and company you’re applying to. Talk about your coding projects and make them relevant to the tasks you could be doing. Make sure you’re researching the companies and be authentic.
