Pluspunten
I will try to be as honest as possible - some of the pros are this is a really good place to start your career, especially if you want to make the jump to one of the big banks in a year or 2. Really good benefits as well - good base, free food, insurance fully covered and probably the best 401k match you will find out there(7.5%). New batch of kids out of college every few months start and all of global data is all young kids who end up becoming your good friends since there is nothing to do in the area. You can your time here to try to build up your tech skills or study for the CFA. Take the offer if you have contacts already in Global data that can honestly tell you about the team that the company want to place you in - it's a complete hit or miss and you want to make sure you don't get stuck for 18 months on a useless team wasting your time.
Minpunten
I mentioned they bring in a fresh batch of kids in every few months - There's a reason for that. The turnover is incredibly high and the reasons for these have been stated lengthily in the other reviews. Probably about 75% of the data teams are complete BS. Most of your job will be manually tagging data day in and day out cranking out work items. Then you will be assigned a block of time where you have to do troubleshooting for clients and their questions. Nobody can escape this, everyone who is an analyst has to do this. It can be manageable if you are on a big team where you might be assigned to do this once a week for a few hours to doing it multiple hours a day. The actual "data analysis" works probably comprises of a small part of your day unless you are an extremely motivated individual who stays in the office for an extra 10 hours a week to do these projects on your own. It is crucial that you find contacts within global data that can give you an honest picture of the data team that you get the offer for. There are some very good teams that are working on exciting projects under talented managers and if you get onto those teams then this should be an auto accept. One of the other things is that it is an unfortunate cycle where the talented folks quickly learn that they either got stiffed by a bad team/manager, or reached a professional/educational growth ceiling in their role. Since the management structure is extremely flat, these folks leave within 1-3 years. Because of this, the middle of the road analysts stay and end up becoming horrible managers. There are of course some amazing managers, but this is the exception not the rule.
