I worked at Deloitte for 2 years in a different geography. I was working there on Cloud DS/DE projects. During the 2 years I spent there, I did feel I was not assigned work to my potential - I kept feeling I was under utilized. However, having said that, now that I look back to those 2 years- I feel that it has given me a good foundation in terms of the vast variety of things I worked on. That's what a consulting firm does to you, work on a bunch of different things based on client needs. You would never work on projects that big tech companies call 'super cool'. A thing to note is after those couple of years, I became hard for me to switch from consulting to non-consulting since I mostly only get interview calls from consulting firm. But this is not the same as doing a summer internship. I would not think much before joining Deloitte, based on the current market trend, i'd go with a strong brand name.
