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.

Made it to "semifinalist round" where I was extended an offer to conduct zoom interview with a few senior program staff, but dropped out after accepting a different offer. This was after submitting a virtual interview, which was very intuitive and gracious in unlimited time to prepare answers before submission.
