Applied through Glassdoor and received an email from HR to set up for an intro. HR pushed back the interview another week later. Finally spoke to HR on spoke after 3 weeks from applying. Talk went smooth. She said she would reach out to me about setting up a technical interview next week. Next week passed by but no call. The following week I have emailed to remind about the interview. Got a reply that the position have already been filled. Very unprofessional and disappointing.
