I am graduating this April in computer science. With my knowledge of linux, freebsd, perl ,research and problem solving skills, I just got in a junior sysadmin job at my University. I don't have connection with the workplace so I know I am qualified because of my skill.
Perl is essential part of the tools I use day to day. but it's not the only one I use. I am sure a lot of us here don't have a title as 'perl developer'. As to the people who are, I think it's best to caputer some more skills along the line if you want to have opportunity to expand.
