My first contact with Zapier felt fairly quick, but the process ended fast or felt abrupt. One time I did a video screening by HR and was rejected within two days with a short explanation that they were moving ahead with someone else, without much clarity on why.

Another time, the process stayed polite and consistent with updates, but it still dragged on longer than I expected because of holidays. I got the usual check-ins and then eventually a decline after about two weeks. In another application, I was told the process wasn’t moving forward after two days due to a timezone preference that didn’t match what I could offer. I also had a longer “still reviewing” delay before a rejection that didn’t include feedback and felt impersonal.
