Vantaggi
Flexibility to work from home. Lesser probability to regress in your career. You may get the opportunity to work on emerging tech. Scope to grow and assume more responsibilities as the company is still not mature in it's practices.
Svantaggi
No credible growth opportunities. This shows in willingness to hire for positions from outside rather than grow people into roles. The organization has been through a period where employees were compensated poorly and still continue to be. Newer employees would easily out-earn existing ones. Don't stay here beyond a few years as it would be fiscally irresponsible. Also note this in the context of no growth opportunities. Average quality of employees. A few stars here and there. But the rest are simply average or below average. Not everyone in the open source community is great to hire, and sometimes the company forgets this. Lack of appreciation for viable business models. Some projects exist for the sake of vanity of the project leads, with no viable business model behind them. If there is any model in the rare event, it is involves legacy systems and solutions used by customers. Competitors outshine this so-called stalwart of opensource when it comes to sponsoring and releasing projects with customer validation. Late to advances in various fields and resting of former laurels. The management is coasting along on achievements of the past, and on revenue earned from migrating legacy systems that were formerly revenue earners for competitors.
