10 Effective Tips for Live Coding Interview
Live coding is a type of coding interview in which the interviewer and candidate collaborate to write code during the interview. This can be done either in person or over a video call.
In live coding interviews, the interviewer will typically give the candidate a prompt or problem to solve, and they will then write code together to solve it. The interviewer will be looking to see how the candidate thinks through the problem and writes code that is clean and efficient.
Live coding interviews can be a great way to assess a candidate’s technical skills, as well as their ability to think on their feet and work under pressure. If you’re considering using live coding in your interviewing process, be sure to give the candidate ample time to prepare beforehand so that they can be successful.
The purpose of a coding interview is to assess a candidate's ability to code on the fly and think through problems under pressure. This type of interview is becoming increasingly popular as it provides a more realistic assessment of a candidate's coding skills.
During a video interview, the candidate is given a prompt and is expected to write working code within a limited time frame. The interviewer will then assess the code for correctness, style, and efficiency. This type of interview can be challenging, but it is a great way to assess a candidate's coding skills in a real-world setting.
Tips to Conduct a Live Coding Interview
Live coding interviews are a great way to assess a candidate’s technical abilities and see how they think through problems. In a virtual interview, the candidate is given a coding problem to solve while the interviewer watches. The interviewer can ask questions and give hints, but the goal is for the candidate to solve the problem on their own.
Live coding interviews can be used for any level of candidate, but they are especially useful for assessing mid-level and senior candidates. There is no one-size-fits-all answer to the question of how to conduct a live coding interview, as the best approach will vary depending on the specific role and company.
However, there are some general tips that can help you ensure that your live coding interviews are as effective as possible in hiring the best developers.
Make sure the problem is relevant to the role
The problem should be something that the candidate would actually encounter in the role they’re interviewing for. This will give you a better sense of their abilities and how they would approach the problem in a real-world scenario.
Give the candidate adequate time to solve the problem
Don’t rush the candidate or try to rush them through the problem. They should be given enough time to think through the problem and write some code. A good rule of thumb is to give them about 30 minutes to solve the problem.
Be clear about what is expected
Before starting the interview, be clear about what is expected. The candidate should know how long they have to solve the problem and what kind of output is expected. This will help them focus on the right things and not get bogged down in details that are not important.
Be available to answer questions
The candidate should feel comfortable asking questions if they need clarification on the problem or the expectations. Be available to answer their questions so that they can focus on solving the problem.
Give feedback after the interview
Give the candidate feedback on their performance after the interview. This will help them improve their performance for future interviews and understand what they need to work on. Live coding interviews are a great way to assess a candidate’s technical abilities.
Make sure the role is a good fit for live coding
Not all roles are suited for live coding interviews. For example, if the role is more focused on design or user experience, then a live coding interview may not be the best way to assess the candidate's skills. Similarly, if the role is more junior, then a live coding interview may not be necessary.
Give the candidate a clear prompt
The candidate should know what they are being asked to do before they start coding. This may seem obvious, but it's important to avoid ambiguity. Otherwise, the candidate may waste time trying to figure out what you want, or they may produce code that doesn't actually answer the prompt.
Be prepared to give feedback
You should be prepared to give the candidate feedback on their code as they are writing it. This feedback can be positive or negative, but it should be specific. For example, if the candidate is struggling with a particular concept, you can provide a hint. Alternatively, if the candidate is doing well, you can praise their understanding of the problem.
Be aware of your own bias
It's important to be aware of your own biases when conducting a live coding interview. For example, you may be more likely to hire a candidate who is similar to you in terms of background or experience. Alternatively, you may be more likely to hire a candidate who codes in a style that you prefer. It's important to be aware of these biases and to try to avoid them.
Take your time
Live coding interviews can be stressful for both the candidate and the interviewer. It's important to take your time and to resist the urge to rush the interview. This will help the candidate feel more relaxed and it will give you a better opportunity to assess their skills.
Also, don’t forget to keep the below tips in mind,
- Develop a clear and concise job description that outlines the key qualifications, skills, and experience required for the role.
- Post the job description in as many places as possible, including online job boards, company websites, and social media platforms.
- Develop a robust screening process that includes both an initial phone screen and in-person interview.
- Ask each candidate the same set of questions during the interview process to ensure fairness and consistency.
- Take your time when making a decision and don’t hesitate to ask for additional information or clarification from candidates.
- Check references for each candidate before making a final decision.
- Make sure to extend a formal offer to the candidate you’ve chosen and provide all the necessary information and paperwork.
- Follow up with the candidate after they start the job to ensure they are settling in and meeting your expectations.
- Be open to feedback from your team and candidates on how the hiring process can be improved.
- Keep track of your hiring process and performance data so you can identify any areas that need improvement.
By following these tips, you can conduct a successful live coding interview that will help you find the best candidate for the job.
Overall, live coding interviews are a great way to hire the best talent. They allow you to see how a candidate thinks on their feet and solves problems in real-time. This type of interview can also help to weed out those who are not as prepared as they should be.
