The candidate's solution is a good attempt at solving the problem. However, there are a few things that could be improved.
First, the candidate does not mention what the input and output of the function are. It is assumed that the input is a singly linked list and the output is the reversed singly linked list.
Second, the candidate does not mention any edge cases that need to be considered. For example, what if the linked list is empty? What if the linked list has only one node?
Third, the candidate's explanation of the while loop could be more clear. In particular, it is not entirely clear what is happening when the current node is set to the next node.
Overall, the candidate's solution is a good attempt at solving the problem. With some clarification, it could be a great solution.
