Hi there,
I thought I would share my experience as it may be helpful to others. I applied to the Earth Sciences MSc program for Autumn 2020 as well as the ESOP. On January 31st, I received an email to schedule my ESOP interview via skype. The withdraw button disappeared from my application on February 3rd. I had my skype interview on February 4th. It lasted about 20 minutes and he mostly asked about my motivation to study at ETH, wanted to know more about my bachelor's program because I study at an American university, and we also discussed my pre-proposal for the master's thesis. He also said acceptances for both the master's and the scholarship would likely be communicated in March. This morning, February 6th, I received an email that I have been accepted into the Earth Sciences MSc program. The withdraw button also reappeared today.
Hope this is helpful! Good luck to everyone!
