Pros
Those professionals left standing are, for the most part, hard working, intelligent and consciencious. They do attempt to provide quality service to their clients across the full spectrum of financial products. They have a massive footprint in almost every market globally and their aren't many things they cannot transact as a bank.
Cons
Senior management is terrified of public perception. It almost felt as if they'd rather have happy headlines than happy employees and stock holders. Morale is awful. Barclays did not grow organically in the United States post the Lehman acquisition. The result of that has been 6 years of purges and downsizes and business realignments. Barclays wants to be the biggest and has lost sight of the fact that its more important to be the best at a few things than very mediocre in everything. Compensation, by all acounts, is 20-30% lower than counterparts at other similar shops.
