Honestly, the interview process was a roller coaster. The total time it took from being contacted by an HR rep to actually signing an offer was months long. I know this is probably common for large corporations, so be prepared for this. After a phone call with HR, I next had a phone interview with the hiring manager. This was followed by a number of other phone interviews - I spoke with two peers, the manager's boss, the bosses boss, and finally had an in-person interview with the hiring manager. In between each of these rounds I waited several days (sometimes weeks) with no feedback. Making it to the next round was a total surprise each time. So I want to stress that you shouldn't be discouraged by the amount of time it takes to hear anything. They are all very busy and hiring someone new that requires training and on-boarding is pretty low on their list of priorities. The interviews were very low-stress and conversational. They asked fair questions and didn't try to stump me the way other interviewers have. They wanted to know about my background and specifically my experience and skill-set relevant to this position.
