About a month after I applied for a PM position, I received an email asking me to submit my availability for an interview. I waited one week to hear back with a confirmed time. When the HM did not reach out, I sent a follow up email to check in and see if anything else was needed from my end. Again, no response. It's been a month now and I don't expect to hear back. Extremely unprofessional to initiate an exchange with an applicant just to leave them hanging. I wouldn't apply at this company again.
