First screening call scheduled with HR but was cancelled and rescheduled 15 prior to the start. Second call attempt was successful, a typical screening call from HR. Moved forward to the next step, I sent availability for a second call but was not confirmed, so I voluntarily stepped out of the process for other opportunities. The person from HR was nice, but the process looked for me a little bit chaotic. I think it´s a good opportunity if you are in your 20s and wanna learn and speed up your career on a start-up.
