IMO, I would use MX 134 as it is a pheromone that demands respect to the wearer and is a nice mix for work. I would also use Instant shine which would also help with the endearing you to coworkers and gives you confidence. but you asked which one product so I would have to go with MX134. However, if you take a look at this post you can best decide for yourself which would better suit you.
I am sure many of the wonderful forum members will give you even more pointers.
Wish you the best of success in your interviewing.
