Unfortunately, this post discusses the expenses and difficulty of hiring, but doesn't provide any information about the compensation offered, nor do I have any real sense of what the position requires. Are they offering 200k for an entry level crud developer? Are they offering 100k for someone with a PhD in Math, an extensive 10+ background in high scale software development at a large silicon valley company, and intricate knowledge of cutting edge data science algorithms? I understand that this information is difficult to release for all kinds of reasons. But without it, it's essentially impossible to evaluate why this company is having trouble filling the position, or whether the added costs for dealing with the visa process are considerably less than the higher salary it might cost to hire someone already authorized to work in the US.
