Recruiter reached out to me via whatsapp and gave me only 3 hours to respond to ask if i want to proceed. when I reached out to explain why I responded late, i got ignored. Very unprofessional

Initial cold call to head of project management services for Detroit; opportunity with a financial services client in the Detroit area; interviewed on the phone with the account HR director; on site interview with the account director out of TX. No follow-up communication for weeks from anyone until I called the HR Director to learn the position was filled.
