When you're new to a company, you have to learn every aspect of it. Staying in your own little cubical and not coming out is not going to help you nor the company to grow.
Even though I was hired as an office manager, I knew I wanted to learn in-depth about our product as well.
So when our founder Jurgen hired me, he immediately planned a workshop for me to learn everything there is to be learned about strain gauges.
So, am I an expert now? No. But when in conversation, I know what it's about. I know what the main principals are, and I can engage with clients on the subject.
Other things I do once in a while is join Jurgen on an installation on-site. Also very insightful.
