A friend of mine who has water-treatment engineering degree recently moved to another country but struggles to find a job in his field. Because he did not want to stay at home unemployed (and because stealing food is not an option), he took a minimum-wage job (salesman in a small shop) that has nothing to do with his skills or even experience.
While I believe there is no shame for him to do that, I'm still not sure what to advise regarding his public LinkedIn profile and/or resume:
Should he mention the low-paying, unrelated job ? Is there any drawback in doing so ? Any drawback in not doing so ?
