Unemployed and not having luck with interviews. Does this work history look like a job hopper?

I got laid off during a company wide restructuring. My job history goes like this with the most recent at the top:

Job #5: July 2015 - July 2018

Job #4 (Part-time on-campus experience during full time grad school; graduated in May 2015): Aug 2014 - May 2015

Job #3: Oct 2011 - Oct 2012

Job #2: July 2010 - Sept 2011

Job #1: May 2008 - July 2010
