I am currently in the process of completing a UK research masters in economics at the age of 26 and have a decision to make. I can go into industry now, or continue and get a PhD in 2-3 years, finishing at 28-29. Recently I have been seeing a lot of events specifically for PhD's at McKinsey and BCG organized by various European Offices.
Any insights here on the best course of action from here on out, i.e. staying on for 2-3 more years for the PhD (and thus applying for an advanced qualifications post-MBA role) or applying straight away (which means applying for an entry-level role)?
