I applied online and received an email that I made it to the first round which consisted of a one-sided interview that we had only a little over three days to complete. For the interview we had to answer four questions, but were allowed unlimited takes. This was a stressful process that took well over five hours to complete. Even after all the time spent crafting answers and re-receding takes so it would be half decent, no one from Mellon ever followed up. Based on other posts it seems like this is normal behavior from them.
