This afternoon, I received an email from Mike stating that Mr. L (owner of business) would like to offer me the Accounts Receivable Clerk position. I promptly expressed my interest and requested a phone number to contact him for more details. However, it has been several hours since my response, and I haven't received any communication. To follow up, I sent another email providing my contact information. I am curious whether it is usual to not hear back after being informed of an offer via email for an extended period of time.
