Espey Mfg. Production Assembler interview questions

I was contacted by this company by their HR department for a position I applied for. We exchanged emails with this company several times and was told I was being referred to hiring and I should expect a call very soon. Two weeks later, no call. I reached out and contacted them regarding this. They told me they would get back to me ASAP. It’s now 4 days later with no contact. Very unprofessional with their follow through.
