I think it would be great if there was a section or thread on this forum listing the most commonly used software companies use. Many packages have PLEs now and so it’s just a matter of bandwidth for people to access the software.
So, if you want to increase your employee marker, put the software you use in this thread. It would be a shame if software became the filter for new talent. Afterall, the more people in this industry the more chance it has to survive.
