A 15-20 minute phone call that I thought went well. Interviewer told me she would reach back out within a week or so. Sent a thank you email the next day, no response. I waited about 10 days as I know how things can get. Emailed asking for a follow up, never heard back. Absolutely rude, disrespectful, and unprofessional behavior to ghost a candidate. If I wasn't selected that's fine, but don't say you'll contact me, I follow up with a thank you and another email inquiring, and just give not a single response. Ridiculous.
