nobody tells you this before you enroll. let me just lay out what the recruiting calendar actually looks like for MBA internships, because I learned it the hard way.
if you're at a top-20 program, the formal recruiting process for summer internships starts terrifyingly early. here's roughly how it goes for a class starting in August:
october - november: consulting firms (MBB, T2) do most of their first-round screening. if you want McKinsey, Bain, or BCG, you are already behind if you haven't started networking in September. case interview prep should have started in August.
november - january: banking and finance recruiting happens in this window. most of the big banks and boutiques close their lists by January.
january - march: tech recruiting happens here. this is when Google, Amazon, Microsoft, and most tech companies open MBA PM, strategy, and engineering roles. the timeline is more compressed and a bit less codified than consulting or banking.
march - april: everything else: startups, mid-market companies, healthcare, government, non-traditional roles. these are often more flexible but also less structured.
what catches people off guard: the consulting and banking timelines start before you've even been in school for a full semester. you're networking, studying cases, and trying to understand your new city all at once.
my advice: if you know your target industry before you enroll, start prep over the summer (before orientation). for consulting specifically, get a case prep partner from your future cohort as soon as the facebook group opens. for tech, the timeline is more forgiving but you should have your 'why this company + why product/strategy' narrative ready before October.
one mistake i made: waiting until the official career center calendar kicked in to take recruiting seriously. the career center is behind the actual market by design. follow recruiting timelines from current students, not the published schedule.
