The insurance company representative assigned to your claim called you yesterday and left a message that they want to interview you. You couldn't sleep last night worrying your long term disability claim is about to be terminated. You are not sure if an interview is typical or not, but its sounds very threatening.
Don't worry, you should not necessarily be alarmed. An insurance company interview is a fairly common part of the claims process. Indeed, it happens with about 50% of the clients we represent. While typical, you need to be prepared to explain you disability prior to the interview.
