Online coding interview and how to CodePair remotely

The reason why you give a coding interview to a software development candidate is to make an educated guess of how well they will do their job if they are hired. This post will tell you the best way to give an online coding interview with a remote CodePair, also know as a pair programming skills assessment interview. It will also tell you how to provide a better candidate experience by code paring remotely.

A lot of the popular methods for interviewing software developers predict their success about as well as a crystal ball. What you want to see is how your developer candidates perform under real-world conditions. At the same time, you want to make it as painless as possible for your candidates to take the test.

An online CodePair interview gives you a window onto your candidate’s development process. It is as close to a real environment as you will find anywhere.

An online CodePair interview is only part of a technical interview. For more info, tips, and tricks check out The ultimate guide to the technical interview.

But it’s important not to cut corners by using outdated methods. To help you avoid that, we have compiled a list of best practices for holding CodePair interviews remotely in an efficient way.

By the end of this article, you will know

What happens in an online coding interview?

In most coding interviews including an online coding interview, a candidate is asked to uses their coding skills to do a certain task.

These tasks can include:

  • Doing a very basic task like inverting a binary tree
  • Writing an algorithm
  • Fixing a piece of code
  • Performing a business function

The interviewer watches the candidate complete the task and asks questions. These can be about why the candidate made a certain decision or how the candidate would react to a change in the task.

An online coding interview should show the interviewer how the candidate would react to similar situations if they were hired. Because of this, an online coding interview should give a task that mirrors your candidate’s first day of work. While inverting binary trees and building algorithms are popular types of tasks, they do not tell you much about the candidate. A good software developer won’t be inverting binary trees or building algorithms on a daily basis. They have tools that can do this.

What is a good task for an online coding interview?

A good online coding interview task should be a task that the developer would tackle if they started working for you.

Your coding interview should represent an authentic work sample, under the same conditions that your candidate would face at work.

This means giving them access to all of the resources they would normally use. After all, the best software developers know how to use frameworks, libraries, Stack Overflow, Google, and a number of other online resources to produce clean efficient code within deadlines.

If you want to know how they use all of the available resources around them to solve your business problems, why would you ask them to forgo these resources?

The qualities of a good coding interview task

  • The test is an authentic work sample
  • It gives your candidate all of the resources they would normally use at work
  • It bases the task on a business problem they will face when they start working for you

Now that you have a good coding interview task, you can hold the interview but a thorough test can come at a cost. The amount of time you will need to devote to a thorough test can cause a problem for some candidates.

The Stack Overflow 2021 developer survey found that only 3.5% of respondents are actively looking for a job. If a developer is not actively looking, it is probably because they are already employed. Your candidate might be interested in what you have to offer. That said, it can be difficult for them to take time off in the middle of the day to interview with you. This becomes even harder when the candidate lives in a different city. So how can you make the experience better for the candidate?

How remote online coding interviews make it easier to test candidates

There is a risk that busy candidates won’t find time to attend an interview in the middle of the day that happens to coincide with when the interviewer was available. Instead, they end up dropping out of your candidate pipeline.

When the candidate is traveling from out of town, coordinating the interview can become even more difficult. Holding an online coding interview is a great way to get around this issue. By removing travel time, it adds a lot more flexibility to schedule the exam.

But to conduct an online CodePair test, you need a tool that will allow you to both communicate with your candidates and see what they are working on.

It is easy to have an online coding interview and CodePair with DevSkiller

By the end of this section you will know how to:

  • Set up an online CodePair interview using DevSkiller
  • Communicate with your candidate
  • Review the code written during the interview

DevSkiller already allows you to conduct an automatic first day of work test on your candidates.  This can be conducted at the candidate’s leisure and works great as a tech screen. Our online CodePair interview means that the tech screen and interview can be folded into one, saving the candidate’s time.

It starts simply enough. The interviewer sends the candidate an invitation to one of DevSkiller’s many pre-prepared tests.

The candidate will then need to start the test at a prearranged time and the interviewer can join the CodePair test.

Once the interviewer joins, they have full real-time access to the same IDE that the candidate has. The interviewer can then work on the project with the candidate, deleting or adding code. Pretty cool, huh? But what if you want to conduct an online coding interview using CodePair?

DevSkiller has you covered. While the candidate and interviewer work on the same code, they can video chat within the app. This way the interviewer can ask questions and gets to know what the candidate is thinking about as they do the interview.

Additionally, the interviewer can focus on subtasks so they can get insights into each step of the process rather than just having the big picture available to them.

The interviewer’s access to the IDE is particularly useful. This is because the candidate and interviewer can run unit tests as they go along or generally see if the code actually does what it is supposed to do.

And at the end of the interview, all of the actions in the IDE will be recorded so the interviewer can review how the CodePair interview went and take notes on the candidate’s decisions.

How to hold your first online coding interview

The best place to start is with your tech lead. They will know the kinds of tasks that the candidate will be tackling on their first day.

They should build a task that has these qualities:

  • Addresses a business issue
  • Is given under real-world conditions
  • Is of an appropriate difficulty for the job

Your tech lead can use DevSkiller to build a task using your own code or they can choose from DevSkiller’s extensive library of premade tests. Your technical interviewer can then hold the interview with a candidate anywhere in the world. You will get a strong indication of the candidate’s future performance while eliminating barriers that can hurt candidate experience.
