Pros
You will make good work. No company will ever push you harder, make more outrageously ridiculous requests from you, and push you beyond the limits of your capabilities. You will probably leave more capable than when you started – with a new found understanding of the importance of saying ‘No; that’s impossible’ and 'You don't get to decide if you're inspirational' to future bosses. That being said, I think Cult is probably wonderful to engage with as a client, but it's like buying something made in a sweatshop or full of palm oil - you just need to make the choice to not think about the process of getting you what you want.
Cons
It's very likely you'll crawl out as a shrivelled husk of your former self – bereft of personal life, confidence totally beaten out of you, feeling incapable of anything – despite the fact you’ve just worked harder, faster, and on more things that seemed impossible than most people ever will. As plenty of people have mentioned, the co CEO’s and those in their inner circle are, and I do not say this lightly, vicious bullies who publicly shame and chastise. Hard work is seldom rewarded or acknowledged. Minor slip-ups (which will happen when people regularly work late into the night and over weekends) are blown out of all proportion as the management live in fear of losing a client. The rate and regularity with which people quit, and the difficulty in recruiting to fill those gaps is really telling. It also means that those who haven’t got out yet are left under ever increasing pressure as teams and support systems shrink, whilst the demands being made of them remain the same, or increase in an attempt to over-service clients. The co-CEO's make a real effort to appear warm and loving and use the word Family non stop. If this is a family it's an abusive one based around the false support of a forced sisterhood, a failure to meet basic HR HR needs and requirements and parents who will stab you in the back at any moment. They are charismatic leaders, manipulating and controlling everything, making Cult the perfect name for that they have built.
