Pros
Decent hiring standards. Small team sizes that enable fast movement of ideas. A less than bureaucratic workplace. Some of the US based managers are so awesome with the way they field client calls and weekly meetings and you'd definitely learn a thing or two in time management. Technology wise, there is decent opportunity in working with leading internet OEMs and picking up solid skills in L2/L3 network engineering. Good appraisal process (for salaries).
Cons
Insane work loads. Forget having a work life balance. Time difference between India and California makes it difficult for engineers to sync. Engineers often have to stay late or report very early to get some face time / call time. New graduates are going to gain little by joining, especially the folks who have little inclination towards L2/L3 network engineering. It is possible that you may feel underutilised or overworked without any real skill development. Enforcement of service agreenments. Not so great growth opportunities (though the same cannot be said about salaries). Tough luck if you want to get a foot in the door into management because you may stay an engineer for a really long time at embedUR.
