<p>If a student takes a year or two off after graduating, would any LORs they’ve received from their professors as an undergrad become somewhat irrelevant? Perhaps in their place LORs received from internships or recent employers would need to be used?</p>
<p>I think it’s generally still a good idea to get at least one letter from a professor. If you’ve been working since leaving college, you should try to get a letter from your supervisor.</p>
