Ventajas
You will probably join a great bunch of like-minded and friendly graduates. The social aspects of the training programme are also good.
Desventajas
How the course leaders dress up the first weeks as “training” is frankly hilarious. In reality they are judging how good you are, and will quickly fire whoever doesn't meet their standards without a care in the world. You can argue this is just normal for all jobs, but no, this is most peoples first job after university and its meant to be a 12-month programme, and within a matter of weeks I saw a handful of graduates break down in tears. Their confidence was shot to bits due to the pettiness of some of the “constructive feedback” - including how people look and act which is outside their control, I will say. I voluntarily left during the 12-month programme (along with a couple others) and it was the best decision I ever made. The pay is bottom of the barrel, the hours are long (they expect more than 9-5), the work is tedious, you have to track everything you do to 15-minute periods (O yes - fun!) the management is nonexistent, the pressure is high, HR couldn't give a toss about any of your complaints because they'll just side with the manager, the list goes on. By far the worst job I've ever had, and if you're a graduate I highly recommend not pursuing this.
