Vantaggi
They will hire you with no software knowledge, and train you well technically in 1-2 years. You'll get as much responsibility as you want to take on, and plenty of exposure to lots of complex technology. There's a decent starting salary for a graduate, and some very flexible working hours.
Svantaggi
After 1-2 years, the remuneration becomes uncompetitive. Base salaries are low compared to other software jobs for your level of experience. There is little or no further training in e.g. management, personal development, certifications etc, and few career opportunities beyond the purely technical. The company has an uncertain commerical outlook, so right now there's some pretty low morale and whether any bonuses will be paid is uncertain.
