Sometimes I wonder if small companies are just full of bitter google rejects who have decided to make the interview process miserable to boost their own egos. I went through a year of being unemployed not too long ago and it was very painful. Receiving no feedback is the worst part by far.

A recent project required some work in jquery. All of the other developers stated that it would be difficult and take them too long because they were not familiar with it - being react devs themselves - so it was left to me. I was shocked. The idea that jquery could possibly be described as being more difficult than react is amusing at best. Sure, it was largely an excuse on their part, but I was left speechless nonetheless.

I guess my point is that nearly 20 years of dev experience leaves me with the ability to do the old and the new. I wish this was more respected by companies in general.

No offense meant, but if you are surprised about the existence of Scrum Masters, then that interviewer is not at all wrong for wondering if you have enough Scrum experience.
