The demand for hiring qualified tech talent in the IT industry has been increasing for a while. With more industries and businesses going digital due to technological advancements, the need for top-notch tech experts is growing yearly.

However, as the demand for hiring top software engineers continues to rise, filling tech roles becomes even more challenging. A survey revealed that 86% of hiring managers and technical recruiters need help finding and hiring software engineers.

According to IDC, software engineers have become a valuable resource for any industry or company due to the shortage of full-time developers, which is projected to increase from 1.4 million in 2021 to 4.0 million in 2025.

This creates numerous hiring challenges in the IT industry, making it difficult to fill positions with skilled tech professionals.

As a result, many are seeking better ways how to interview senior software engineer. However, before we dive into that, it's important to examine some of the main challenges that tech recruiters face.

Challenges you might encounter as you build your tech team

• Limited pool of candidates with relevant technical skills
• Market competition
• Time-consuming interviews
• High costs of hiring software engineers
• Lack of formal IT education

Now that we mentioned the common engineer hiring challenges, here’s how to interview senior software engineer with planning and tweak how you strategize the hiring process.

1.Here are a few ways on how to interview senior software Engineer

I. Live coding interviews

Live coding interviews are challenges or exercises that mimic real work a candidate might do on the job. The candidate is assessed in a pair programming interview, in which they will interact directly with the existing tech team on a project. Some of its benefits are:

• Live coding interviews make the most sense if you want to hire for a coding-only position. This method is best for assessing senior role positions, which require a lot more than coding abilities. It evaluates how someone thinks through code and approaches problems and how they will lead others.
• The coding challenges typically include something close to what the candidate would do on the job. The candidate can also complete the challenge in a reasonable amount of time.
• Candidates can’t cheat with live coding. The skills demonstrated by them are completely practical. For example, a candidate may have mentioned they know what a singleton pattern is, but do they know how to write one or recognize one in a code?

Live coding interviews help track precisely this! The candidate will apply their knowledge and walk the technical interviewer through their work in detail.

Some other skills you can check during a live coding interview include:

1 - Oral communication: how easily can a candidate explain their thought process or understanding of the coding challenge?

2 - Openness to feedback or different opinions: how do they take feedback or criticism from the interviewers?
 

II. Coding assessments 

A coding test is an efficient process to screen a senior developer before hiring them. These technical assessments enable you to identify and hire proficient developers. So, coding tests are your go-to if you want to hire quality developers.

Tech recruiters can use a skills assessment platform to conduct coding tests. These platforms will enable you to test applicants in a specific programming language or over multiple technologies (Java, Angular, Python, etc.).

You will be able to screen a large number of candidates in a short time, and cut bias from the entire recruitment process. Coding assessments help filter top candidates and identify if they are a good fit for your organization.

III. Take home projects

Take-home projects are another way to assess the skills of a senior developer. These assessments consist of real-world coding tasks that candidates can complete independently. Candidates can use a coding environment, including libraries, frameworks, and access to GitHub, etc.

Here are some benefits of take-homes:

• It gives the candidate enough time to do the work in a comfortable environment.
• A take-home project will enable hiring managers to assess how candidates think through problems.
• A good take-home project mimics what the candidate might be asked to do on the job.
• Take-home projects will remove a lot of stress associated with other technical challenges.

IV. Examine their programming portfolio

Programmer portfolios are the best way for developers to showcase their skills. These portfolios can include single web pages to complex software projects. Any passionate developer will have one, as it allows them to showcase their coding skills.

Think about it this way: You would only hire content writers if you read their previous articles.

The same logic applies here.

You can see a candidate's skills and development level with a portfolio. In other words, the main benefit of examining portfolios is to know a candidate's previous projects and gauge how helpful they would be for your team.

v. Include a senior developer in the technical interview process portfolio

Conducting a technical interview during the recruitment process is a vital responsibility.

Here’s why you should involve a senior developer to conduct the interviews.

Senior developers have a wealth of experience and knowledge they bring to the table. This can significantly benefit the company in its hiring efforts.

Let’s discuss why a senior developers should be involved and the benefits they bring to the table.

i. Technical Expertise:

One of the main reasons is their technical expertise. A senior developer is well-versed in the technologies and programming languages that the company uses. This makes them the best people to assess a candidate’s technical skills.

They can ask challenging questions and determine a candidate’s level of proficiency in a particular language or technology. This ensures the company hires the right developer with the necessary tech skills. Thus, contributing to the team and driving the company forward.

ii. Objectivity:

A senior developer can help provide an objective assessment to test a candidate’s technical abilities. This will avoid any biases arising from past experiences or personal relationships. Conducting technical interviews is one way to assess the candidate’s tech skills objectively, ensuring that the company makes informed hiring decisions.

iii. Company Culture Fit:

In addition to assessing a candidate’s tech skills, a senior developer can also test a candidate’s soft skills like problem-solving approach and communication skills. This will give an insight into how the candidate would fit into the company’s culture and team dynamics.

A senior developer will also be able to determine if the candidate has the interpersonal skills required to work effectively with the test of the team.

iv. Industry Insight:

A senior developer has a wealth of experience in the industry and will offer valuable advice and perspectives on current and emerging trends. This will help an organization make informed hiring decisions and stay ahead of the curve.

For example, when hiring a senior developer, the company can tap into their expertise and knowledge to ensure that they are hiring people who are well-equipped to drive the company forward.

In conclusion, involving a senior developer in the technical interview process ensures that the company is making informed hiring decisions and cultivating the next generation of technical leaders within the organization.
