The internal recruiter has reached out to me on LinkedIn asking for a call. We had a call and he said he would come back to me with the feedback next day. I have never heard back from him, even though I have sent him an email. I am deeply disappointed - not having any courtesy of sending a ''Thank you email', even though I was rejected, is quite frankly disrespectful. Candidates prepare for interviews and not having any feedback after the interview call is very rude. I have never expected this level of service quality from the company like Slack.
