Ventajas
They only have one client, but it is a well known international bank (Santander). Working for such a big client is interesting for one or two years and looks very good on your CV.
Desventajas
Extremely low starting salary and long hours. Only work with one client. Not a strong consultancy name to have on your CV. No pension fund or dental insurance. I've been told you do not get a bonus in your first two years and you can get a bonus of 1 or 2 thousand pounds after your third year... no comments. Locally hired graduates only stay for a maximum of one or two years (the time it takes them to find another job), the rest of the office are Spanish expats who have their flats in London paid and high daily expenses. After a few years they buy a house in Madrid with all the money they have earned and go back to Spain, then the company sends new expats. In the mean time new locals get hired every year because they need to substitute those that leave. Just terrible, nearly pathetic. I was lied during the interview process about the number of clients. They try to make you sign then you see the truth. I wish you had not lied to me. Lately HR is trying to compensate for all the bad reviews the company has received here in Glassdoor and are posting good reviews every two weeks (check reviews with 4 stars in 2014), trying to cover up is even worse.
