Devskiller provides three ways to generate the Tests.

Choosing a Predefined Test:

For my review first I decided to test the predefined tests area. And to be honest I was impressed by the ease and relevancy of tests i can choose from.  

One of the Good thing was the possibility to choose tests based on the specific role. For the review i decided to Choose "Java Middle Developer Test".


Auto Generated Test:

The next thing I tried was the auto test generator wizard. It takes few seconds to generate any new test you want.

And there are various options. You can use the core language or add some related frameworks as well.

As shown in the screenshot below.



Once you are finished then just press Generate test and it will create a test in few seconds.

Inviting Candidates:

Once you are done generating a Test. You can click on candidates. And then by clicking on invite Candidates.

You can send the test to the candidate you wish to evaluate.

 Candidate's Perspective:

The candidate will receive an email with instructions and link to the test. Once he clicks on the link he will see a screen like this.

Devskiller Vs Other Tools

As with anything else in life Devskiller is not the only tool available in its space. 


The real question is what other options are available and where does Devskiller stand in relation to other tools in the market. 

Based on my impressions after testing Devskiller for more then 2 weeks. Here is how Devskiller competes with other tools




Testing Ability



Devskiller Summary

After my extensive testing of Devskiller. It came out  as a Winner in Candidate Assessment Segment. Mainly because of its wide coverage of programming languages and frameworks.

But also the quality of questions and tests is very high. Anyone without technical knowledge can generate a test in seconds.

And the results of the test are very thorough and gives a meaningful overview of candidate's performance.

Technical recruitment process is very cumbersome and is full of infinite complexities.

In order to save time and energy companies can leverage the power of Tools like Devskiller to filter out the best candidates for the job.
