<p>When employers talk about GPA are they talking about overall GPA or in-major GPA?</p>

<p>Whichever one is higher. ;) If they want details, they'll ask.</p>

<p>Ditto, put whichever one that's higher on your resume.</p>

<p>should I specify which one it is though?</p>

<p>No. Tell them only if they ask.</p>

<p>Ditto what everyone else said, and I'll add more...</p>

<li>If in-major GPA is higher (and over 3.0), mention that one</li>
<li>Of grad-school GPA is higher than undergrad (my case) mention that one.</li>
