I use Observable's platform and am on their mailing list. I responded to the "Observable is Hiring!" section of an email. A few days later was told they would like to learn more about me, wanted to schedule calls over the next few days with members of the recruiting and engineering groups; asked about my availability. I was out of the country and told them I could easily be available any day between 10a and 2p Pacific time. They asked if I was permanently out of the country; I answered it was temporary and gave them the date of my return flight to the US (~18 days later). Never heard from them again. Followed up: no response.
