Promised to deliver high quality and within two weeks. Confident he could finish this and he should be hired and no one else, because of his knowledge. After hired I didn't get any updates, ever. Had to ask and ask for progress. 2 weeks went by and still no update from him. I asked for update, where he responded he wanted more money to continue, bad thing. I gave him the raise but only if he updated and communicate through the project. 2 weeks went by again, still no update. Then he dropped out.
