Pros
None that I can think of but being up to date and aware of the tactics of these companies is always useful. They will often change their name so be vigilant.
Cons
This company contacted me presumably because they got my CV off a jobsite which I have now privated after this occured. This company also used certain filters in their email ex. strange symbols in the company name, presumably to bypass spam filters, they also contacted me through a fake recruitment agency and all of this makes me sure they know that what they are doing is a scam.
The job is not a marketing job it is door to door sales, you will be self employed and paid on comission and have to work very hard to make any money at all. You will have to work long hours and attend team building events etc which are all a cover for the fact this is an MLM scheme. There are unfortunately a lot of these companies operating in London and have become much harder to avoid as they mask themselves now on recruitment sites as shop-assistant jobs and so on. Be vigilant about these predatory companies.
