I received an invitation for a virtual initial interview from a company on Monday, and I promptly replied with my availability. However, since then, I haven't heard anything back. I followed up with an email yesterday, but still no response. Today, I called the number provided in the email, but it went straight to voicemail, and I left a message with my contact information. I'm starting to feel anxious about the lack of communication. Am I being too impatient, or should I consider that they might have ghosted me? I'm in a tough spot looking for work, and this was the only opportunity that progressed this far.
