I applied to Tulip (a few years ago at this point) several times (either on the website or LinkedIn), including applications and follow-ups to that very e-mail address. I never once got a response, positive or negative or otherwise. It always felt a bit weird, especially given my experience. I thought I'd give that feedback since I happened across this.

Also, a few of Tulip's job descriptions list Elixir as interpreted, which isn't correct.
