How to screen front end developer skills – HTML and CSS

記入例 コーディングテスト, フロントエンド開発者, インタビューの質問, IT人材紹介

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.

How does the average person hire a top-notch tailor? They ask the candidates to show them what they’ve stitched so far, maybe even ask them to sew something fast. Then they’ll observe the results, noting how well they operate the sewing machine, the organization of the workplace, and assess the tailor’s attention to detail. Are they wasting too much fabric or simply not doing a very good job?

How do software developers hire top-notch tailors? Well, it would probably go a little something like this; This is a whiteboard. Please draw the difference between Ghiordes and Senneh knot. Derive the length of thread as a function of fabric’s surface area”.

Honestly, I believe that a top-notch tailor should know the difference, but what are we really verifying here? Do you want an elegant jacket or an elegant equation on a whiteboard? 続きを読む

C や C++ の開発者は、他の言語の開発者ほど話題になりません。JavaScript の開発者ほどユビキタスではありません。Python の開発者ほど、データサイエンスのようなホットな話題には縁がありません。Kotlin の開発者ほど新進気鋭の技術を使っているわけでもありません。しかし、これまでの技術とは異なり、C と C++ は、組み込み技術やゲームのような分野だけでなく、多くの重要なシステムの主力であり続けています。その結果、CとC++の開発者に対する需要は依然として多くあります。そこで問題となるのは、C および C++ 開発者のスキルをどのようにスクリーニングするかということです。

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.

Screen .NET Developer Skills Set List & Experience Requirements

記入例 コーディングテスト, IT人材紹介, 採用のヒント

You are about to start a recruitment campaign to hire a .NET developer or a .NET Core developer. But once you receive your applications and resumes, you have to decide who is good enough to get to an on-site technical interview. This requires a technical screening process.

技術系の採用担当者の多くが気づいていないのは、以下のことです。creening involves more than glancing through a resume. Why is that? On the one hand, good .NET developers are scarce so you don’t want to overlook a candidate with potential and good programming skills. On the other, you don’t want to invite weak candidates for an interview. This wastes the precious time of your IT team and coworkers.

そこで問題になるのが、.NET開発者候補者の.NETプログラミングスキルをどのようにスクリーニングして、優秀な候補者を面接して、悪い候補者を除外することができるのかということです。私たちは、.NET技術で何が重要なのか、どのように迅速かつ効果的に候補者をスクリーニングするのかを示すために、このガイドをまとめました。準備はできていますか?まずは基本的なことから始めましょう。 続きを読む

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. 続きを読む
