What to look for in front end developers

Front end development is the area that refers to everything you can see, touch, click, and use. This includes the visual layout, user interface/interaction (UI), and user experience (UX). Front-end development is known as client-side software (as opposed to server-side software), and consists of a range of buttons, images, links, and pages that all need to function harmoniously for pleasant user experience.

When assessing the skills of a front end developer it’s essential to ensure that they possess a strong knowledge of both HTML and CSS. In addition, they should be adept and proficient with both JavaScript and TypeScript. Staying up to date with the most common JavaScript frameworks such as jQuery, Angular 2+, and Backbone js is a must. A high level of experience with UI layouts, SASS, LESS, Bootstrap, and the CSS GRID system is desirable as is solid experience with using REST API from the client-side. Finally, demonstrated experience with debugging using JavaScript-based tools like Chrome Developer Console is important for a front-end developer candidate.

Criteo

Criteo is a global leader in commerce marketing with advertising solutions that allow B2B companies to build personalized ad campaigns across multiple sectors. Every year, Criteo hires approximately 100 technical profiles globally for their operations teams.

Prior to implementing DevSkiller, Criteo candidates were tasked with a take-home case study that was used as a first filter before interviewing with the team. This screening procedure came with many challenges such as the impossibility to track completion, limited insights into how the project was completed, candidates dropping out, hiring delays, and unnecessary interviews.

The solution? Introducing an easy and efficient screening method to combat these challenges.

“We use DevSkiller in 15 locations around our 3 regions (US/APAC/ EMEA). We have 7 frequent users in TA (recruiters) across our regions and our technical hiring manager users rotate depending on current needs. More than 30 have logged into the platform once to review an assignment or create a test.” – Julien Gautiez – Talent acquisition manager EMEA at Criteo

Perguntas mais frequentes

O que é o RealLifeTestingTM?

The RealLifeTestingTM methodology serves as the basis of all DevSkiller frontend coding tests.

Rather than quizzing the candidate with games or algorithmic puzzles, the methodology provides a 360-degree view of a developer’s skills. At its core, The RealLifeTestingTM stems from the belief that the best way to evaluate a developer’s development skills is with a work sample test that mirrors the actual development work they’ll do. Our coding tests require candidates to build full project apps or add features to existing apps, just like they’ll be doing after being hired. To do this they will need to show their knowledge of coding, in stack resources, resources like Stack Overflow to find solutions and decision making to find the best way to solve the problems they encounter. The automated results provide insight past the candidate’s academic knowledge but also their coding ability, critical thinking, and time-management.

How are front end interview questions and online tests evaluated?

Quando o candidato termina o seu teste, a plataforma começa a trabalhar automaticamente na avaliação da solução. O resultado é um relatório que até um recrutador não técnico pode compreender. Os candidatos são avaliados quanto à capacidade de execução da solução (um fator essencial em todo o desenvolvimento de software), à existência de erros no código, à qualidade do código e à forma como funciona em casos extremos. Existem também funcionalidades robustas de plágio que mostram a semelhança dos resultados com soluções anteriores.
