What to look for in a DevOps engineer

A DevOps engineer’s role is to support agile software development. The position was created to bridge the gap between a traditional software developer and an operations engineer. It can also be referred to as SysOps or SRE. Screening DevOps engineers is often tailored specifically to the exact skills the employer is looking for. There is no standard set of required DevOps skills, but some of the following will be helpful.

A DevOps engineer needs to possess the soft skills required to be able to collaborate effectively with the rest of the DevOps team. They might also possess knowledge of a number of technologies, ideally, in those your business already uses. It will be a positive if they possess the skills to configure many systems using automation tools.

A DevOps engineer also needs to know their way around tools and scripts to be able to solve any issues that crop up along the way. Depending on the specifics of the position for which you are recruiting, security management testing skills can also be important to look for as well.

Our Devskiller DevOps interview questions will be able to help assess an engineer’s configuration management skills, as well as assessing ability in writing configuration management code.

Want proof that our DevOps interview questions work?

It might be that you’re interested in our DevOps interview questions but would like a little assurance. That’s completely understandable. Check out the following case study of one of our satisfied clients:

Criteo:

Criteo is a commerce marketing company that is one of the global leaders in its field. The company has advertising campaigns targeting businesses across the retail, travel, and education sectors.

Previously when it came to recruitment, Criteo undertook a huge amount of interviews. Candidates were asked to complete a case-study at home, but there was no way of knowing where the candidate had gained the information. It was also very difficult to keep track of the progress of each candidate. This all led to huge delays in the company’s hiring process and inconsistencies across the company’s 15 sites. They turned to DevSkiller.

Using DevSkiller, Criteo hires for approximately 100 technical positions, across 15 sites each year and the company now has one consistent recruitment method in place globally across all of their sites.

DevSkiller automated Criteo’s recruitment process and helped the company to cut down on the number of interviews. We also helped to filter out the less-qualified candidates meaning that Criteo now interviews an average of only 3.5 candidates for every one person hired.

Our system is automated, meaning several candidates can still be assessed for each role, but these are filtered out automatically, leaving only the most qualified left to be interviewed. Thanks to DevSkiller Criteo hires around 100 new employees each year and saves between 2-4 days on each hire.

Julien Gauthiez – Talent Acquisition Manager EMEA at Criteo

“Per every hire, we’ve saved on average 2 to 4 days which is significant given that we hire 100 people using DevSkiller every year. We’ve certainly improved the conversion rate between the first and second interview with fewer candidates dropping at test stage and hiring managers interviewing with the most skilled candidates,”

Frequently asked questions

How long does it take to set up DevSkiller?

From start to finish, DevSkiller testing will quicken up your current recruitment process. Testing can be undertaken remotely to save time on in-house interviews. It is also remarkably easy to set up our DevOps interview questions. Our experts have prepared an extensive catalog of tests that only need to be sent out via email. Just set-up your account and begin testing candidates straight away.

Do I need to be a programmer to use DevSkiller?

Our team has done the hard work so you don’t need to. Devskiller is as simple and automated as possible to allow anyone to be able to use it, regardless of their technical capabilities. We have a range of ready-to-use DevOps tests designed to allow users to verify the technical skills of even the most senior of candidates. If you are technically adept, then you can prepare your own custom tests from scratch.

What do candidates think of DevSkiller tests?

The feedback we receive from developer candidates is very positive. Developers are often tested in ways that don’t necessarily reflect their actual development skills. This is not the case with our DevOps interview questions. Developers appreciate the structure of Devskiller tests and that our unique approach using RealLifeTesting™, allows them to really show what they can do.

Instead of having to remember coding patterns and algorithms they probably haven’t needed in years, developers are asked to implement normal coding tools and conventions the likes of which they encounter everyday in their work. This makes the whole testing process much more natural for the candidate and means the results you see are much closer to how the candidate will actually perform in the role.
