Listen you big, dumb, balding north american ape...
Given your background it might be more appropriate to get into industry-specialised consulting rather than a generic strat house as they will be able to factor in your chem doctorate and project mgmt experience (for example, consulting for the Oil & Gas industry). You need to demonstrate that you can apply this knowledge to their business area and that you have sufficient other skills to make it at higher than grad entry level.
Otherwise you will indeed be lumped into an analyst / associate intake where nobody's previous experience matters and become a spreadsheet jockey for 3 years.
