How can I verify if a person works for IBM or not?

Question

There is this person who claims to be working at a very high post (Regional level) for IBM. How can I verify if he/ she works there?

Answer 1

Call at the regional office and ask to be given his/her voicemail. If s/he works there, you will get a voicemail message. If not, they will tell you there is no one by that name there.
