VERY UNPROFESSIONAL!!!
Got an email saying that 'all of them in the team are welcoming you as an applicant in our hiring process' and asking me to submit my availability for a phone screen. I sent my availability immediately without any confirmation back. One day later, I sent another email asking whether the interview had been confirmed. Still no response. 10 days later, I sent my last email showing I'm really interested in this role and asking if it possible to reschedule the interview. Finally, she replied me saying that all roles got filled already and they don't hire anymore.
