Pros
makes you really question the tangiable difference that ridiculous companies like this have - 'you are progressing research'? If you were you'd actually bring in academics and not charge a premium for a glorified networking event. Linkedin is free - whats really the point.
Cons
'throw enough different conferences at a wall and one will stick' mentality. exploit graduates by rinsing and repeating a high volume of staff. the turnover is high and this is entirely reflective on the company culture and it's model. It essentially uses graduates to pedal likely to fail products while leaving luck of the draw to those that succeed. Your productivity or input will not determine your success or commission - yet they love to say they are a meritocracy.
