You’ve taken the classes…
You’ve programmed the projects…
And now it’s time to get the job you’ve been gunning for.
The next, and perhaps final step, is nailing the interview.
Coding interviews are notoriously stressful and agonizing, in large part because of the difficult questions you’ll be asked.
Knowing beforehand what will be asked and having a great answer can make the difference between getting called in for your first day or trudging along to yet another interview.
In this post, we’ll show you 50 of the top interview questions you’re likely to be asked so you’ll be well-prepared to give solid answers.
But before we do, let’s take a look at a few tips for making the interview as smooth as possible.
Before sitting down for an interview, you should know as much as possible about the company and the person interviewing you.
Look for the products and projects they’ve created and are working on. Use some of their products if possible, and be able to speak intelligently about them.
Identify the core technologies and frameworks they use in coding.
Have a general understanding of their target market and niche domain they operate in.
Look up the interviewer on LinkedIn. This helps you “know your audience.” An HR director probably won’t understand a lot of technical jargon, so you should prepare a different approach to the interview with them than you would with a lead software engineer.
Researching before the interview allows you to have relevant talking points and displays your genuine interest in the company. But perhaps more importantly, it gives you a clear idea of how your current skills align with the job requirements and lets you assess how well you’ll fit in the organization.
The first interview might be your only shot at a great first impression. Although you’re applying for a job that doesn’t require outstanding social and soft skills, being personable and confident goes a long way in making you stand out from other candidates.
Be energetic without being frantic and enthusiastic without being obnoxious.
Give a proper handshake and make consistent eye contact.
Being friendly and likable also demonstrates to the interviewer that you could be a great team player. If hired, you’ll be working alongside many other software engineers, stakeholders, and members of other teams within the organization. Your communication skills will be weighed against your technical abilities when deciding who to hire.
Your body language and that of the interviewer can largely dictate how you’re perceived as a candidate and how well the interview goes.
Being sweaty or clammy in an interview can make you seem unable to handle the pressures of the coding job you’re applying for.
Bad posture can make you look lazy, even unattractive, and can trigger unconscious biases in the interviewer’s mind.
Tapping your foot, fiddling with a pen, or nervously playing with your hair can be extremely distracting to some people and make you come off as unfocused, too hyperactive, and possibly unable to be productive and work the demanding hours of a coder.
Those are just 3 examples of your own body language to pay attention to.
Calming yourself as best you can, sitting with proper posture, controlling your body movements, smiling, etc. are positive nonverbal cues that silently influence the interviewer toward liking and recommending you, increasing your likelihood of being hired.
On the other side of the table, you should pay attention to the interviewer’s body language.
If you give a long response to a question and the interviewer clears their throat, for example, this may tell you to be more concise in your answers.
Focus on how the interviewer reacts to your answers to understand how to keep them engaged, maintain a good conversational flow, and possibly even turn the tide of the interview if you notice it’s going south.
The coding interview questions you’ll be asked are designed to judge your ability to talk about software broadly and in fine detail.
Your resume will list the projects you’ve performed in the past and the interviewer is likely to probe into them.
If the question is vague such as, “Can you tell me about this project?” Don’t launch into the deep technical aspects right away. Tell a “story” about its creation, starting from the front-end application and what you used to develop it, through to the user inputs that informed its design. Then work backward to the modules within the application all the way to the persistent data database.
By noting every level of development and the specific software programs used for them, you demonstrate a deep understanding of the total infrastructure of a given project and the capability to execute these same tasks for their organization.
These coding interview questions and tips can help you do well in the interview and get hired.
But like we mentioned in one of our tips: technical skills aren’t all you need once on the job.
Communication skills are almost as important as your ability to code.
But here’s the thing:
Emails, texts, calls…
None of them possess the persuasive power of showing your face or visually demonstrating what you’re talking about.
Programming is all about problem-solving.
Visual communication helps you reduce miscommunication and mistakes when solving problems with your team.
Creating a GIF to capture a bug and sharing it in a pull request or on Slack, GitHub, Jira, or anywhere else your team communicates speeds up understanding without relying on confusing messages or calls.
