Applied on Indeed, got an email to apply on their website, and got a call for an interview in a week. Interview is scheduled for the next day. Emailed a bit and interviewer in emails was very responsive at the moment. Entry level questions about what my experience is in Java and other career questions.
Asked when to expect a call, and was told I would get a call in around 2 weeks. Sent a thank you email within 24 hours. It's been over 2 months since then. I followed up with 3 phone calls, a voicemail, and an email with no response.
Never been ghosted this hard by anyone, let alone in a professional space.
