A process as follows.
1. Got contact from the in-house recruiting team via Linkedin and had a phone interview re background and JD
2. Had a F2F interview with one of head of the vertical team
3. Had a mock sales presentation session to one of the head of the vertical team and creative director at Creative Shop
After 3rd interview, the in-house recruiting team suddenly stopped communication and have not got any feedback yet after 6months. Surprised to experience such an unprofessional attitude.
