ActiveCampaign Software Engineering Internship interview questions

The most unprofessional recruitment experience I have ever encountered. After approving my CV, HR scheduled a specific time and date for an interview. I joined the meeting on time, but the recruiter completely ghosted me and never showed up. To make matters worse, I never received any follow-up, explanation, apology, or even a standard rejection email. Complete radio silence after standing me up. Total lack of respect for a candidate's time.
