So I have given the coding round for internship in Newzera and Barclays and in both these rounds the general format was that there was one visible testcase and you would be told whether your code gives the right answer for that , for the remaining testcases we were not told whether our code passed or not. I wanted to know is this the usual practice or is it something specific to a few companies. That is do we atleast get to know whether the code passed on the hidden testcases>
