9 reasons why

Adaface Hive Test is the most accurate way to shortlist 它是虚拟管理员s

Reason #1

Tests for on-the-job skills

The Hive Online Test 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:

有效地编写和执行蜂巢查询
展示对蜂巢数据类型和内置功能的理解
优化蜂巢查询以进行性能
将蜂巢分区和存储库用于数据组织
实施Hive加入和亚克斯
利用蜂巢视图和用户定义的功能
使用蜂巢外部表和加载数据
管理Hive数据库，表和元数据
了解蜂巢查询优化技术
使用ETL过程实施Hive数据转换
利用蜂巢索引来提高查询性能
故障排除和调试蜂巢脚本和查询

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.

How we design questions

这些只是我们库中有10,000多个问题的一个小样本。关于此的实际问题蜂巢测试将是不可行的.

🧐 Question
Medium Analyzing Hive Join Optimization	Solve
Consider the following two Hive tables in a space adventure context: Assume that the astronauts table is small and can fit in memory. Which of the following queries will take full advantage of a map-side join?
Medium Hive Archive	Solve
You have a partitioned Hive table sales_data with the following schema: You want to archive the oldest partition (date='2023-01-01', region='North America') and store it in the Hadoop Distributed File System (HDFS) at /archive/sales_data. Which of the following steps is the correct approach to perform the archiving operation? A: Enable archiving on the table, and then issue an ALTER TABLE statement to move the partition to the archive directory. B: Issue an ALTER TABLE statement to move the partition to the archive directory, and then lock the partition to prevent further modifications. C: Enable archiving on the table, and then use the EXPORT command to export the partition to the archive directory. D: Use the EXPORT command to export the partition to the archive directory, and then lock the partition to prevent further modifications. E: Use the EXPORT command to export the partition to the archive directory, and then drop the partition from the sales_data table.
Hard Jobs file	Solve
Assuming the following Hive statements execute successfully, choose the correct statements that describe the result: A. Hive reformats JobsFile2 into a structure that Hive can access and moves into to /user/steve/fenty/ B. The file named JobsFile2 is moved to to/user/steve/fenty/ C. The contents of JobsFile2 are parsed as comma-delimited rows and loaded into /user/steve/fenty/ D. The contents of JobsFile2 are parsed as comma-delimited rows and stored in a database

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment 蜂巢测试 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 蜂巢测试 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.
