Vantaggi
No pros that stands out, CEO tries to increase the valuation of the company to sell it (it looks like that) so you might get some benefits from that (though unlikely). Will be good financially for next ~6 months as they cut more and more RnD and will just get money from producing legacy stuff
Svantaggi
Company that pretends to be ethical and pretends to care about employees that in fact just cares about numbers on the sheet and will mercilessly lay off people and close viable projects. As an employee be ready to be a part of slow moving (sometimes even dysfunctional) company with compensation and benefits below average. Senior management only cares about numbers and outlook to try to sell the company in the future. In many cases senior management does ridiculous things since they don't fully understand what they're doing. Does not care about employees at all, company loyalty is not valued at all. Be prepare to be laid off with bare minimum severance and no bonuses, RSUs, nothing. Senior management that is incompetent will be glad to lay off people for cheap, though they will tell everyone how "ethical" they are and how they care about people to find their new "home".
