Senior Full Stack .NET Developer

Notes: Must be this to get the offer. This is very important! If they aren't exactly the below- they will get DQ'd. If you find the below, they will get the job.

1. Have strong true full stack experience. Expert backend .NET with experience using C# and F# with strong hands on Angular experience. Lean backend. A lot of "full stack" candidates will be 70% front end. This role needs someone who can live in C# + SQL + integrations.
   
   1. What is F#? --- F# is a Microsoft programming language that runs on the .NET platform, like C#.
   
   

The simple way to think about it:

C# = mainstream Microsoft language
F# = more specialized .NET language often used for math-heavy, data-heavy, financial, analytical, or functional programming work
