<p>I just got rejected from a R&D internship. But another internship just opened up at the same plant. This one is more on the industrial side. Would it be a no no if I apply to it?</p>
<p>Apply to it. You never know.</p>
<p>It is never a no-no to apply to anything unless you are in the period between accepting another offer and starting that job.</p>
<p>If you were rejected before, the worst that will happen is still that you get rejected again. No downside whatsoever.</p>
