A 3.6 does not make an MBB application pointless. It may be below the strongest academic profiles in some pipelines, but the degree rigor, school context, work or research achievements, and overall application all matter.

If the GPA is your main concern, this guide on getting into consulting with a lower GPA explains how to strengthen the rest of the signal.

Your engineering background can also be positioned around problem solving, quantitative work, and technical leadership. The engineering Master's to consulting guide is useful for translating that experience.

Apply rather than self-reject, but make sure the resume shows impact beyond coursework.

3.6 engineering is not some disaster. I'd apply.

Research bullets need to sound like outcomes, not just methods.
