I worked at the company where as a first filter we had a remote coding task (roughly 2- hours of implementing some simple data structure plus unit tests). A candidate sent us a prefect solution indicating very good knowledge of Java, testing framework, clear thinking, good problem solving etc. When the candidate came for the live interview she was absolutely shocked that we asked her coding questions again. "But I have already did the coding task!". It was very clear that she didn't know how to write a line of code if her life depended on it. I wonder what was her plan if she got hired by mistake.
