I am looking at this job posting. I find the salary of $100k questionable for a job in the solar industry in the region. The company's website exists but isn't great. I think it's unlikely but possible that the job posting is real. For example, they may be a start-up that received a big windfall from somewhere. Or, more likely, it is a scam.
I know there are other questions on here about how to tell if a job offer is a scam: obviously I won't give them any money, and I'll be careful about personal information, as much as is possible and still apply for a job. That being said, I don't want to miss the opportunity if the job is real.
So, what are the signs that the above linked job posting is or is not a scam?
