Colloquio
The recruiter called and scheduled an interview over the phone. No prior information was given about the type of interview and what to expect.
The interviewer was nice. Asked a bunch of questions and verified answers from his playbook. Also, provided feedback.
After the interview, I followed up few times with the recruiter and they never responded.
Very unprofessional experience.
