Remote work is not for everyone - it requires you to be extremely self-disciplined, self-motivated, and accountable. In a lean, fast-growing company, that can feel like you always have way more to do than time to do it. You have to be able to create structure to your day, prioritize, and not get flustered or overwhelmed by knowing that there are competing priorities. It sounds easy but can be challenging in practice.
Being remote, you have to be more deliberate about everything including getting out of the house, building a strong social network outside of work, and taking the initiative to communicate with colleagues.
Being results-oriented means that no one will be micromanaging you to get things done. You have to be willing to speak up when you need support.
I don't personally see these things as a con because there are ways to manage them, but you do have to learn how to manage them.
