What to look for in a Ruby developer

Ruby is a dynamic, general-purpose programming language quite similar to Python. It was built with a focus on simplicity and productivity and its syntax is remarkably easy to read and write, making it ideal as a server-side scripting language and for use in front-end applications.

In looking for a new Ruby developer, it is important to take into consideration that Ruby and Ruby on Rails are not one and the same. Ruby is a programming language, whereas Ruby on Rails is a framework that simply uses the Ruby language. There are other frameworks that use the Ruby language too, like Sinatra for instance, so it is important to find out which framework your developer uses.

A Ruby developer will also need to possess knowledge of the language’s libraries, which are referred to as gems. The gem system is easy to scale and has developed to the point that it is completely standardized. It is also important for Ruby developers to be up to date with any changes in the language, as a new version of Ruby is released basically every year.

If your business requires a developer that only uses Ruby as a scripting language, then they also need to know the basics of Linux, networks, and other system basics.

Within the Ruby programming language, there are two big libraries for testing, RSpec and minitest. One would expect a decent Ruby developer candidate will know one of these, but a brilliant one will have used both and be able to describe the main differences between them.

It is understandable to be a little wary of investing your company’s money into our screening tool, so if you’re still unsure, here’s what our other customers have to say:

Sabu Pappu - Talent Acquisition Lead hos Veriday

"Vi har reduceret den tekniske afvisning, hvilket er fantastisk. Vi har set en forbedring på 25% på dette punkt efter implementeringen af DevSkiller. Platformen hjælper os virkelig med at vurdere kandidaternes programmeringsfærdigheder og giver os en logisk tilgang til it-professionelles problemløsningsfærdigheder. DevSkiller sparede os for en masse tid, mens vi havde en opstart, og hjalp os med at invitere kandidater af god kvalitet, der har klaret sig godt i testen, hvilket i sidste ende forbedrede udvælgelseskriterierne."

Richard Williams - VP of engineering hos Plutora

"Takket være automatiseringen af screeningsfasen kunne vi reducere antallet af samtaler med 50%. Samtidig er kvaliteten af de kandidater, der når frem til interviewfasen, nu meget højere. DevSkiller tilføjer et ekstra lag af kvalitet til vores tekniske ansættelsesproces"

Patrycja Kiljańska - Specialist i talentindkøb hos Spartez

"Vi har erstattet en intern løsning, der krævede meget vedligeholdelse, med DevSkiller. Vores proces ser ud som den samme, men produktet giver os en bedre ydeevne. Resultaterne er også meget nemmere at vurdere."

Ofte stillede spørgsmål

What’s the exercise duration?

Each DevSkiller Ruby interview coding exercise has an in-built, default duration which can be easily altered to suit your company’s preferences. It is also possible to set time limits for individual questions within a test.

How do candidates complete a Ruby interview coding exercise?

Our Ruby interview coding questions are carried out remotely to allow developer candidate’s to access the exercises at a time and place that most suits them, while also saving time and money on in-house testing. All a recruiter needs to do is send out the test invite. Each test invite can be made available for a specific amount of time so there is no waiting around and the candidate can simply complete the test and send it back for evaluation once they’ve finished. Tests are marked automatically. During the exercises, candidates have the option to use our state-of-the-art in-browser IDE or complete the project on their favorite IDE and then clone the project to GIT and they can also run- unit tests to make sure their solutions work.

Can a candidate cheat during a Ruby interview coding exercise?

In short, the answer here is no. At DevSkiller we take plagiarism very seriously and as such, we implement a number of tools, ranging from screen recording, to social listening, to ensure that your business receives only valid results in return. Our plagiarism detector also automatically checks the code each candidate has entered as well as their answers, against those of previous test subjects and automatically flags if there is a match.

Skal jeg være programmør for at bruge DevSkiller?

Certainly not. All of our Devskiller Ruby interview coding exercises are deliberately designed to be as non-technical and as automated as possible. Our ready-to-use tests are prepared by our experts, which takes the pressure off you, while also meaning you can recruit for positions much more advanced than your own personal skill set allows.
