How to screen front end developer skills - HTML and CSS Blog

Wie man die Fähigkeiten von Frontend-Entwicklern prüft - HTML und CSS

Durch Kodierungstest, Front-End-Entwickler, Fragen zum Interview, IT-Rekrutierung

HTML and CSS are two of the most fundamental front end developer skills. You’d be hard-pressed to come across a web developer who doesn’t have at least a basic understanding of the two stalwarts. However, some believe that HTML and CSS shouldn’t be given the same respect as other languages because neither requires any internal logic. That’s because HTML and CSS are declarative languages that instruct a web browser to render web pages rather than use computational code.

Despite what some may think, it’s becoming increasingly valuable for developers to possess in-depth knowledge and expertise of theses two languages. Verifying a developer’s HTML and CSS skills is as important as ascertaining skills in languages like Java and C++. Surely, anyone vaguely technical should have a basic understanding of HTML and CSS. In the end, that’s all you need, right? Not exactly.

HTML and CSS make up the backbone of front end development along with JavaScript. In fact, you’ll also find quite a lot of back-end developers who use these languages on a regular basis. While you will never find a developer who solely uses these languages, HTML and CSS are critical enough to modern software development to ensure that front end developers are able to use them effectively. While they are simple to get started with, advanced applications require in-depth skill and understanding. It’s essential to verify that your developer has this understanding.

Computer programming is the very basis of the digital age that we live in today. Every time you like a post on social media, send an email, or set an alarm on your phone, a programming language is working behind the scenes – pulling the strings. 

But where did it all begin? And what spurred its growth into the leading industry that exists today? Most of all, why is knowing the history of programming languages important to hiring developers?

Join us, as we embark on a tour of the history of programming languages. This retrospective will demonstrate how much computer programming has developed over the years.  It’ll take you back from the early languages and complicated machine code to sophisticated human-readable language that powers our favorite technologies today.

Ich werde nicht an Ihrem Interview zum algorithmischen Test teilnehmen

Durch Kodierungstest, Experten-Interview, IT-Rekrutierung

Wie stellt eine durchschnittliche Person einen hochkarätige Schneider? Sie bitten die Kandidaten, ihnen zu zeigen, was sie bisher genäht haben, vielleicht bitten sie sie sogar, schnell etwas zu nähen. Dann beobachten sie die Ergebnisse, stellen fest, wie gut sie die Nähmaschine bedienen, die Organisation des Arbeitsplatzes und beurteilen die Detailgenauigkeit des Schneiders. Verschwenden sie zu viel Stoff oder leisten sie einfach keine sehr gute Arbeit?

Wie stellen Software-Entwickler erstklassige Schneider ein? Nun, es würde wahrscheinlich in etwa so ablaufen; Dies ist ein Whiteboard. Bitte zeichnen Sie den Unterschied zwischen Ghiordes- und Senneh-Knoten. Die Länge des Fadens in Abhängigkeit von der Oberfläche des Gewebes ableiten".

Ehrlich gesagt glaube ich, dass ein erstklassiger Schneider den Unterschied kennen sollte, aber was überprüfen wir hier wirklich? Wollen Sie eine elegante Jacke oder eine elegante Gleichung auf einer weißen Tafel? Lesen Sie mehr

C and C++: software engineer interview questions

Screen C and C++ Developers Skills

Durch Kodierungstest, IT-Rekrutierung, Rekrutierungs-Tipps, Technisches Interview

C and C++ developers don’t get the same buzz as developers in other languages. They aren’t as ubiquitous as JavaScript developers. They aren’t as well connected to hot topics like data science as Python developers. They don’t use a technology as up-and-coming as Kotlin developers do. But unlike the technologies making all the headlines, C and C++ continue to be the workhorses of many essential systems as well as areas like embedded technology and gaming. As a result, there is still a lot of demand for C and C++ developers. So the question becomes, how do you screen C and C++ developer skills?

Herausforderungen bei der Kodierung technischer Interviews

Wie man technische Herausforderungen bei der Codierung von Interviews nutzt, um die besten Entwickler einzustellen

Durch Kodierungstest, Humanressourcen, IT-Rekrutierung, Rekrutierungs-Tipps, Technisches Interview

Interview coding challenges are a highly polarizing topic. The truth is, you could probably fill libraries with resources to help you master coding interview challenges. That said, what does it take for the employee to create an effective coding challenge scenario?

Interview coding challenges aren’t inherently evil. They can help developers master the art of coding. From the recruiter’s point of view, they can help choose the right candidates. You have to be careful though because they’re a double-edged sword. If done right, they can help you identify the best candidates. If done wrong, however, they can turn your candidates into your enemies and possibly make a bad hiring decision.

[Webinar]From a code plagiarism checker to an IP tracker, DevSkiller’s tests are secure

Durch Änderungsprotokoll, Kodierungstest

It goes without saying that a developer skills test is only useful if you know the right person took the test. In the vast majority of cases, this is not an issue. But we still employ a code plagiarism checker on our system. Why is that?

Why you need a code plagiarism checker

Plagiarism is a big problem in society. According to Academic Paradigms, LLC, The Center for Academic Integrity found that almost 80% of college students admit to cheating at least once.  And if you think that this is simply a case of all those underwater basket weaving students handing in cheap baskets from the Walmart as their end of term project, you would be sorely mistaken.

7 Steps to Hiring Top Developers

If there was ever an image summing up the developer recruitment pattern, it’s the one used by Isaac Lyman in his Medium post “How to recruit a developer”:

Looks familiar, right?

Unless you are one of the lucky companies offering “showstopper” jobs, it’s very rarely that top tech talent comes knocking on your door. Good developers are quickly snapped up because as passive candidates they get subsequent offers. They are almost never on the market because they don’t need to be shopping for jobs. Lesen Sie mehr
