Top 8 interview tips for Full Stack Developer jobs

5 minute read

A Full Stack Developer is an engineer who works with databases, servers, systems, engineering and clients. To put it simply, they can carry out tasks relating to both the front and back ends of a website or application. 

The front end of a website or application refers to what the user can see, such as the final version of a website. The back end involves building the infrastructure that allows a website to look and function the way it does. 

This doesn’t necessarily mean that you would be responsible for writing all of a website’s code yourself, however.

Many spend most of their time in either the front or back end of a site, but have enough knowledge about both to be able to jump in and work on both if needed. 

The day-to-day responsibilities of a Full Stack Developer include: 

  • Aiding with software design and creation
  • Testing and fixing bugs and coding issues
  • Developing, managing and improving databases and applications
  • Creating robust security and data protection settings
  • Building mobile-friendly websites and apps
  • Working with other members of the digital team on projects and software improvements 

Desirable skills for Full Stack Developers include:

  • Knowledge of back end languages such as JavaScript and HTML
  • Experience with databases
  • The ability to develop desktop and mobile applications
  • Familiarity with common stacks
  • Knowledge of all the latest security concerns and best practices to avoid them
  • Excellent communication 
  • Attention to detail
  • The ability to work both independently and as part of a team
  • Organisation skills
  • Being able to multitask (you may for example be asked to move between front and back end projects)
  • Having an analytical mind
  • Project management, visual design and user experience skills are also desirable

Full Stack Developer interview tips 

Congratulations on securing your interview. While this can be a nerve-wracking experience, the more preparation you do, the more confident you’ll feel on the day. 

Below we share seven Full Stack Developer interview tips which will bring you a step closer to getting that dream job. 

1) Do your research 

Researching a potential employer is one of the best ways to become a stand-out candidate. It shows that you’re taking the interview process seriously and that you care about who you work for.

What’s more, the more knowledgeable you are about the company, the more confident you’ll be. 

While you don’t have to go into great detail, make sure you familiarise yourself with the following topics:

  • The company’s culture, mission and values
  • Key players in the organisation
  • News and recent events related to the company
  • The products or services they offer 
  • You should be given the name of the person of people interviewing you so research what they do, what their background is and if you have any common interests or connections. LinkedIn is a great place to find out all this information 

2) Find out the structure of the interview 

If you haven’t been briefed about the format of the interview, a great way to get an insight into what you can expect is to have a look on Glassdoor

Once you’ve created a free account, you can see what previous interviewees have said about the process, what the structure of the interview was and sometimes you can even see the questions that were asked.

This is a fantastic way to prepare for an interview and it will also help to calm your nerves if you know what to expect.

There’s also a review section, where you can see what current or previous employees have said about the company. This is incredibly helpful as you can gauge whether or not you’re the right fit for the organisation. 

3) Research the company culture

It’s important to get a feel for what the company culture is before your interview. As well as helping to determine whether you’re the right fit, it could also shape your interview answers and any work you decide to show.

Some easy ways to find out about an organisation’s culture include:

  • Look at their website. Businesses often state their values, include news updates, a meet the team page and some even talk about the company culture on their site
  • Social media is a great place to find out what a company is like and what it might be like to work for them
  • Glassdoor reviews 

4) Learn the language

Even if you don’t have much work experience, it’s good to familiarise yourself with industry jargon. This will help when specific questions come up such as ‘which back end languages do you have experience with?’

Have a read of ‘Coding jargon: a glossary of key terms’ to get started. You can also read tech news websites and magazines such as Tech Crunch and Wired.

As well as picking up on how industry experts speak, you will naturally encounter commonly used terminology.

 5) Show personal projects 

Taking in any personal projects you’ve built yourself is a great way to show off your skills if you don’t have much work experience. 

Having a portfolio of work you’ve completed in your own time tells your interviewer that you’re passionate about the role, you’re willing to learn, and it also lets them see what you’re capable of. 

6) Practice interview questions

Research common interview questions and how to answer them. This is a crucial part of preparation because the more practice you get, the more at ease you’re likely to feel on the day. 

YouTube is a helpful resource full of tips for preparing for interviews, doing research and being confident. There are plenty of videos such as the one below which will help you to prepare for what might come up. 

7) Follow up

If you’re keen on the role and have the interviewer’s details, send them a friendly email after your interview thanking them for their time.

This also provides you with an opportunity to clear up anything you missed at the interview or to reiterate why you would love the job. 

If you went through a recruitment agency, you can call or email them with the same message which they will be able to pass on. 

8) Enjoy the experience

Our final tip is to enjoy the experience and what you can learn from it. 

Aside from doing your research and practicing the questions, all you can do is be yourself. Remember, this is just as much about you trying to figure out if the job is right for you so don’t be afraid to ask the interviewer questions as well.
