I did not apply -- a recruiter cold called me to talk about the role. I had an initial phone screen with the recruiter and was passed on to a phone interview with the hiring manager. The hiring manager was late for our call. Once on the phone, she told me about her experience, the role, and then asked me a few questions about my background and why I wanted to work at Slack. The last part was a timed editing test, which needed to be emailed to me then sent back in an hour. We agreed to a day and time over the weekend for me to do it, but the hiring manager never sent it at said day and time. She responded to my emails the following Monday, sent me the test and told me to send it back whenever I could.
That was the last I heard from them. A few days after completing the editing test, I followed up with the hiring manager directly to see if the position was still open and whether I was still being considered, but no response. About a week later, I emailed the recruiter asking the same thing, but she also did not respond.
If you cold call someone and start them through the process, it's very unprofessional to then go MIA, especially after multiple emails from the candidate for a follow up. Very poor candidate experience.
