I used to think non JW people looked fondly at such attributes and skills..... now with ten years distance from WT, I would never mention it in a million years.
Here is some perspective, imagine a smiley, clean cut guy walks in to an scientific interview and says expectantly "I'm very good with people, I audited people as a scientologist for 10 years..." or "As a mormon preacher, I developed skills to talk and interact with strangers."
Selling a cult door to door or from platforms is not a skill most are looking for. Don't get me wrong, just like a good scientologists there are Jw's out there with fantastic interpersonal and auditory skills, but it is all in the context of selling untruths, ironically it was wholly anti-science, I would 100% NOT mention it. WT has a reputation of indoctrination, dictatored manipulation without the freedom to question or think for onevself, with a mindset of suspicion for reason and science. From talking to many, many people, to my shameful realisation, when admitting connection to such a religion, at best, the average joe will just think "weirdo." With chemistry in mind, this is the same organisation that said Aluminium was a metal, literally from the Devil.
Having been through UCAS, you simply need the minimum academic grades to not get binned at the starting line, then evidence of your interest in the topic and finally, yet importantly, you need to show them you have extra curricula skills, experience and a good work life balance.
Despite what Watchrower told you all your life, they have hindered not helped.
