Pros
None if you're a good person.
Kontras
Preys on ambitious graduates, stay away. Pyramid Scheme.
It's not a promotional events company in the slightest, you stand on the street pestering people using charities to get their money and bank details! “CEO” personally conducts the interviews selling vulnerable people a dream, vile behaviour.
Entire online presence is a fabrication designed to lure you into an interview, where they sell you an utterly different role to what was advertised and a false business plan. They promise fast-track company development in hope to have you work slave labour so the management can feed their pockets.
They share a tiny office space with around 6 other companies all coincidentally interviewing for the same role, and all the companies are constantly "expanding". (One being Bone & Marrow Co, identical business structure) They're all in cahoots. They take advantage of human psychology and marketing tactics to deceive a continuous stream of applicants.
Zero opportunity for career development, they essentially scam you into scamming other people for them.
