Several interviews, the process takes several weeks (possibly months). First you'll meet with a talent recruitment specialist for a cursory chat they will feel you out a bit, next you talk to talent recruitment coordinator who will also interview you and feel you out a bit, they'll be your guide and aid throughout the entire process, after them is technical screening and after that you'll interview with members of your team (perhaps multiple times). All of the interviews can be phone or skype, if you are out of the area which is nice.
The technical questions are very difficult and performance specific. I suggest reading up and studying hard on dynamic management views, troubleshooting long running queries and etc. The guy running the screening has a loose grip on the English language at best and is often hard to understand. He also has some strange prejudice against Oracle DBAs and databases so if you have experience with that just be sure to pronounce loud and early how you hate Oracle and love SQL-Server.
The rest of the interviews are personality fit and personality type questions and everyone besides the technical ballbuster Indian guy is pretty friendly. Below are technical questions, the personality ones are the same generic ones everyone uses and are not MetLife specific (you can google those).
Overall it's a good process and if you are just starting to look for a switch beyond your agency to giant enterprise like MetLife these types of interviews will harden you and make you better, study harder, etc. for the future.
