These are my thoughts on how a corporate lawyer, with law firm experience, should describe and categorize that experience.
The objective here is to put the space on the first page to the best possible use, to edit out what doesn’t add to the reader’s understanding of your current abilities.
At the mid-level, it’s fine to have the traditional resume which has narrative beneath each job entry, listed in reverse chronological order.
What you want to list in the narrative are the subject matter of your practice—ex., M&A, Bank Finance, etc.—the elements that you have negotiated, researched and/or drafted; what place you were on the totem pole, (ex, member of a team or only associate on 250M stock purchase?); and the industries/business sectors from which the parties to these deals have originated. Reference to kinds of legal regimes is a good idea. Ex, the word compliance is more forceful if you refer to the statute or kinds of rules which are relevant. You should list the types of deals or documents that you have drafted and negotiated.
Recurring activities belong in the narrative. Single transactions belong on the Representative Transactions List. Ex, drafting periodic reports under the 1934 Securities Exchange Act is in the narrative. A singular transaction which might have entailed 1934 Act elements, goes in the Representative Transactions List.
In terms of that list, if the person reading the resume knows your practice, be judicious in the amount of detail you use in describing the kinds of documents you have negotiated or drafted. If you drafted and negotiated a particular kind of deal, which, by definition, includes a long list of major and minor documents, list the major documents only.
Ex: Negotiated and drafted asset purchase agreement and all ancillary documents including x, y and z significant documents.
Put your earlier experience into context. If today you negotiated and drafted the principal documents for a particular kind of deal, at some earlier juncture you likely put together exhibits or did other lower level stuff on a the same kind of deal. You don’t add to the reader’s information about your skills in including that earlier detail. Accordingly, you might, let’s say as a fifth year transactional lawyer, find yourself not providing a great deal of detail on the narrative from a transactional job in the same practice area which you might have held for only two years immediately following law school. In that case, the narrative for the earlier position should indicate the kinds of clients for which you did work, by business sector and size, and the kinds of deals but might not talk about your actions/activities.
You can add something about the size of teams you might have managed and whether you mentored or trained junior associates. If clients are comfortable contacting you directly, that is worth mentioning.
On a separate Sheet, entitled Representative Transactions, list the representative deals themselves should be in the deal sheet which follows.
If you are more senior, it is fine to adopt a functional resume, where there is a summary narrative for all of your transactional experience, followed by a list of dates, titles and places of employment. Your detail on your representative transactions would follow on a subsequent page. The idea here is that the reader should not have to look in too many places to determine your core competencies.
