Ask HN: What its like to develop using BPM technologies?

I'm a software developer. I have been working as a Web/Android developer for one year (HTML, CSS, JavaScript, PHP, MySQL, Java) and also in my free time I enjoy writing in Python/Ruby and learning new programming languages. I usually use Linux/Mac, I like the terminal, Git, GitHub, open source, Sublime Text, Intellij, etc, etc, etc. And now, I have the opportunity to work with BPM technologies (the job offer says: "Design and implement BPM solutions from Functional requirements", "Implement Process flows, Reporting, Data, System and UI requirements using BPM tools", ...).

I dont' know anything about BPM and I have searched about it but I still do not understand it at all. My first impression is that I will have to use WYSIWYG tools and drag and drop elements instead of write code in a text editor ... and I LOVE write code in a text editor. So any advices? Thanks.
