Declined to interview. It was a major red flag when it took the company two months to acknowledge my application, and the email that was finally received was one sentence and didn't even include who to contact or what company was reaching out, not even in the form of an email signature. I had to Google the email to see who was inquiring. Need to polish their communication with potential candidates and not wait so long to follow up, because missing out on a lot of good people in doing so.
