I worked for devere and used linkedin all the time to find people to phone.I would pretend to know someone that they knew, it's called common ground.
You have to lie, cheat and steal it's all part of devere life. It's in their training manual from Malta, we were given the unofficial manual soon as we arrived at our country of destination. This gave us all the untoward tricks & scams we needed to make appointments.
Unfortunately I had to work with a man who could not sell very well so I didn't make loadza money like they said I wood.
