Credit Karma Test Engineer interview questions

Recruiter contacted via phone without any prior notification. Asked if I am interested and asked my availability for technical interview. I texted him the availability and he scheduled technical phone call. Hiring Manager called me and asked few questions about my experience and projects. I told about test framework and he asked what else is there in your test framework the same vague question 4-5 times and I didn't understand and asked him to please be specific. But he asked same question again. Nothing really technical except one question about database management. After interview he said he will communicate feedback in couple of days. I followed up with recruiter about interview but there is no response at all. Not even a single word. Very unprofessional.
