Vertex Global Services interview questions

Called to the office for a face to face interview. The interview was just 15 minutes and I was informed that I would be meeting the CEO next. I wasited for over 40 minutes and then ultimately was told to go home and complete an assessment as the next step. I did so and submitted it within 24 hours. I did not hear any feedback or the result in 2 weeks. The recruiters started ghosting and would cut calls as soon as they heard the candidate. Extremely unprofessional and rude.
