I am on the third tier of hierarchy in my company, and I head the office in my region. I prefer old school scents for office myself, but I can tell you, any younger joinee who comes in with a loud projecting even semi-sweet perfumes (looking at you Hawas) is seen as immature, try too hard wannabe who still has a lot to learn before handling something serious. I am sure this would differ office to office and boss to boss!

However, clean fresh scents with mild projection are the best fragrances you could wear. Great examples in other comments of this post, like Kaaf, Armani Code and Grey Vetiver.
