I was recently interviewed at Verizon ,i got a call from the Hr that i was selected for the role and they asked me to submit my documents but after that there is no communication.I tried calling hr many times , initially few times she lifted the call and told that we will release your offer letter in this week but after that she is not lifting the calls.please let me know how long will it take to get the background verification done and release offer letter because it almost 3 months completed.
