I applied for a role and received an email asking for my availability for an interview. I replied back thanking the sender for their email and listed some days/times when I was available. I still hadn’t received a reply back after 3 days so I emailed again. I received an auto-template email back 3 weeks later thanking me for taking the time to interview for the role but informing me they had selected another candidate. Please take the time to care about all candidates, not just those you hire. This was insulting.
