9 reasons why

Adaface Mochaオンラインテスト is the most accurate way to shortlist node.jsソフトウェアエンジニアs

Reason #1

Tests for on-the-job skills

The Mochaオンラインテスト helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves time by filtering out unqualified candidates at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

データレイヤーを効果的に設計および実装する機能
統計層の分析と操作に熟練しています
イニシャルアイザーのセットアップと管理に熟練しています
テストを正確に実行する機能
Mochaのバックエンドとその機能に精通しています
計算層の操作の能力
ユーティリティレイヤーを効果的に利用する習熟度
ネイティブエクステンションを使用したCPUバックエンドの知識

Reason #2

No trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

View sample questions

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Mochaオンラインテスト in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Science behind Adaface tests

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the Mochaオンラインテスト from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

[プロクチャリング機能]（https://www.adaface.com/proctoring）の詳細をご覧ください。

テストスコアを解釈するにはどうすればよいですか？

留意すべき主なことは、評価が選択ツールではなく排除ツールであることです。スキル評価が最適化され、技術的にその役割の資格がない候補者を排除するのに役立ちます。これは、役割の最良の候補者を見つけるのに役立つために最適化されていません。したがって、評価を使用する理想的な方法は、しきい値スコア（通常は55％、ベンチマークを支援します）を決定し、インタビューの次のラウンドのしきい値を超えてスコアを上回るすべての候補者を招待することです。
