Introduction

The following article presents what are the different stages in the progress of Talend Open Studio For Data Integration certification, specifically version 5.2.


Buying certification


  • You have only to select the desired certification, personally I chose the Talend Open Studio for Data Integration 5.2 certification, which costs $ 100.

  • Once the purchase is complete you will receive an email as below telling you that your purchase has been registered and that you will receive instructions in the next two days to pass certification.


  • Personally I received the email instructions one day after purchase. The email will contain a link to connect to the platform of the test, and your user-name and password. Below you can seen an example of this mail:


Passing certification exam


  • Once you have received the email instructions you can connect to the test platform  and you will see something like this:



  • Then simply click on the link "Click here to Take a Test" and you will be sent to the list of tests:



  • By clicking on the chosen test a "summary page" will be displayed that gives some information to know before you start: 


  • You can notice that the number of questions is 63, to take the exam you must answer 80% of questions, ie at least 51 questions. Another thing, you can not skip a question and come back, you have to answer questions in the order they appear. Finally, it's possible to take a break and return later to complete the test.

  • According to the graphical interface of the platform there is no time set for the exam, no timer is displayed, but it remains to be seen.

Successfully completing the certification

  • After answering all the questions on the test, you will have an instant result telling you whether you have passed and your score in addition to a link to download a PDF version of your certificate:
