First I want to be clear and tell that my answer is not intended to apply directly for this internal recruitment, sorry for this.
Whatever, our little company "PIT Business" based in Luxembourg is a very good Influence Qlik Partner (technical partner, not reseller), and we provide high-valuable pre-sales services on Qlik Sense.
I'm sure we could collaborate to strengthen your pre-sales force on a technical level... And you would be absolutely delighted with the quality of our services !
I know NodeGraph, and I have personally implemented data lineage and documentation solutions, based on Qlik Sense, for big companies in Benelux.
For example, the customization of the Qlik Sense Agent (https://github.com/QlikPreSalesDACH/Qlik-Sense-Agent) to include Qlik Sense Fields, QVDs, IBM Cognos Reports & Packages, DWH tables and operational sources from SAS DI.
Another example, the customization of the Qlik Sense ChatBot (http://branch.qlik.com/#!/project/5a2fb8474666f1a641bc8e76) to work 100% on-premise with Let's Chat and not Telegram.
Feel free to contact me (mathieu.pignon[at]pit-business.com) if you can see some opportunities to enhance your pre-sales projects together.
Thus you will appreciate the quality of services of a human and committed company, composed of technical experts on the excellent platform Qlik.
See you soon,
