I applied. I received an email with a calendly link to book an appointment for a 15 minute phone interview. I didn't book it immediately because I was busy. They called me the next morning and I asked to call them back because I was in te middle of work, they agreed and we set a time. They didn't pick up the phone when I called back. I booked a phone interview on the calendly link and they canceled it. I rescheduled and they canceled it again. It felt like retaliation for not having time when they called me the first time unexpectedly.
