@sumudu I must say that I hate this feeling. Then again, I have been doing things I did not get any formal education for for the past 11 years, so no wonder I feel like this.
I accidentally got familiar with a company that would do things I used to do before I had to change my career. They have open positions, but their ”requirements” are something I never formally got education for. I might know bits here and there, but I am by no means an expert in that subject they are requiring. This made me even more anxious.
