Answer:

Walk up to one of the consultants and ask-

“Is the truthful consultant standing in front of the Executive Interview room?"

If Answer is Yes, walk in THAT door.
If Answer is No, walk through the OTHER door...

Don't believe me? Try working it out on paper.

There are four situations:

(1) Truthful consultant in front of Interview room
(2) Truthful consultant in front of Exit
(3) Lying consultant in front of Interview room
(4) Lying consultant in front of Exit

What is the answer to the question for all four situations?
