During a job interview I was asked if I had any experience with Software Technology X.
I had not.
But I was curious and afterwards I got intensively involved with Software Technology X. I watched countless videos on Youtube and have now even completed an online course on this topic. Additionally I started to develop open source projects with Software Technology X. Unfortunately this technology is not used in my current company.
How can I make future employers assume that I am proficient in Software Technology X even though I am just doing it as a hobby?
