Questions about Master's in Microbiology

I am currently in my last year of undergraduate in the University, completing my Bachelor in Microbiology. I am looking into going into the Master’s program for Microbiology. However, there are some questions I have regarding this path of study. I have been reading around about these things, but I would like some personal/subjective opinions regarding the questions I have. If you just have the answer for one of these questions, that would be fine by me. I just want some information and opinions about this.

What does the Microbiology Master entail? As in, how is the area of study, how detailed is it, etc.

What career opportunities do you have with a Master’s in Microbiology? I know Microbiologist (duh), medical microbiologist, etc. Could you explain what you do in these fields just mentioned, and also in other fields?

How is Microbiology compared to Molecular Medicine, Neuroscience, Biomedical Science, Biotechnology, and related fields?

And last but not least, what is the salary for someone with a Microbiology Master? If you could also tell me in what field of Microbiology this salary is for, I would greatly appreciate it.
