Hi Anonymous,
it is easier to be considered for an interview coming from a top MBA, however you can receive an invitation even coming from a non-Ivy one. I would recommend to network with current consultants with your same background to maximize the chance to be invited – you can find more on referrals at the following link: https://www.preplounge.com/en/consulting-forum/hey-everyonehope-all-is-well-3176
Best,
