The project was fairly straight forward doing some data transformations with some unique file types. I gave back 3 solutions and provided the pros and cons of each and a final recommendation. I get a very angry email back saying they want to see full code/git and documentation not just a report. Seemed a bit off so I provided it for one of my solutions but modding it and burying my signature in some of the functions and comments. I send it off and literally get ghosted follow up calls and emails go unreturned. A couple months later I get an email for some one on linkedin saying they had questions about my previous work. They were from out of the country and got hired into the role but were using my interview project in production for Leidos, and it wasn't even the good one. No one read or reviewed the code obviously before stealing it and putting it into production.
