Screening interview covered basic question about yourself, background, why you are looking to change, what is your team structure, what is the problem you are solving, what is the monthly ad budget, what is the salary range you aim for

The company recruiter reached out to schedule a zoom interview. However, the recruiter canceled the meeting invitation 15 mins before the zoom call. I thought the recruiter map have another interview that went way over and he may need to reschedule, which happens sometimes. Unfortunately, this is not the case. Send a few follow-up emails for rescheduling. No feedback or explanation.
