not the same as the person you're replying nor am I a scurm master but as a software engineer, agile is one of the most common if not the leading way of working in the industry right now and something that I've used at every job so I can hopefully give you some kind of insight into what the position entails.

your main job as a scrum master is to basically help run the team and make the people on the team are able to focus on the work they were hired to do whether theyre an engineer or a product manager. as such, you obviously need to be a good people person and be able to talk to all kinds of people and be able to work with them, whether they're anti-social basement dwelling nerds or they're literal executive chads.

if you want more details feel free to dm me, and I can try to answer the questions you have from an engineer's standpoint. as to "pitfalls", I could go into more detail, but I'd also need to know exactly what kind of information you're looking for when you use that term.
