We have PB standard license. We were  only maintaining  the existing client/server GUI application. 

Need has arise for developing and enhancing existing app. 

HR has short listed some PB developers for interview.  

Need help with some basic and technical PB questions to ask candidates with answers. 

 

Any help is appreciated.

I spent some time this evening composing some technical questions in a Word document for PowerBuilder developer candidates. There is a section containing general PowerBuilder questions and a section containing DataWindow questions. I started a PFC section but ran out of time... I will complete this in the next couple of days.

The zipped preliminary document is attached.

Please see my follow-on post in this thread for the completed document.

I have finished preparing a Word document that contains suggested interview questions for prospective PowerBuilder developers. It contains 30 questions on general PB topics, 16 questions on DataWindows, and six PFC-related questions.

I hope you find these questions useful in your candidate search.

Best regards, John

Addendum:

I'm including the following URL which should allow you to download the Word document from my Google Drive:

    https://docs.google.com/document/d/1ytccTsVYbSfLB1WT-PtP3h2lJtdw8Jpo/edit?usp=drive_link&ouid=100601483811178537991&rtpof=true&sd=true

This was necessary because the Q&A site will not upload the zipped document and show it in this post.

Hi, Gaurang -

Although there are many simple, basic PB questions that can be asked, if it was me in your position, I'd want to ask some questions that would reflect a candidate's ability to successfully maintain MY application. I and others here can probably give you some interview questions (and answers, I suppose ;-)), but first I have a few basic questions for you regarding your PB environment and application:

What version/release of PB are you using? Will you be migrating the app to a newer or latest version?

What version(s) of Windows is being used to host/run the application? Is the app deployed on a Citrix server?

Is the app deployed as a 32-bit app or as a 64-bit app?

Does the app create/send email? Create PDF's (reports)?

Is the application built upon an object framework, such as PowerBuilder Foundation Class (PFC) or Standard Tool & Die (STD)? If not, is there any object inheritance used?

Does the app utilize any Windows API functions or third-party Dynamic-Link Libraries (DLL's)?

Best regards, John

Employ them on 3 month trial, they should be able to complete a small project effectively in that time.
