1. First phone interview with corporate HR in Stamford - very nice was on your side - make sure to email about what to expect for second interview.
2. Second phone interview with local HR manager in Fort Myers - was nice as well.
3. Third phone interview with 2 SMB managers. Each one has been there for over 10 years - make sure you ask questions of how they got there and why they are still there. One of them was very laid back the other one, not so much. He made you feel awful about what you bringing in as though you were interviewing for a "entry level" position (I have over 7 years of sales experience which didn't matter to them). Some of the questions I presented they couldn't answer correctly - they needed clarification, I don't know any manager that couldn't answer simple manager questions.
Overall, when applying and interviewing for this position if they see any flaw i.e., motivation, character trait, the way you perceive competition, not asking the right questions regarding the "value based" selling approach - which you need to dig and dig deeper into the question, personal/professional goals - that need to be carefully planned out specifically of how you will reach them, how you prepared for this interview - annual report (any keywords that you find that you don't know, ask) what you found out within the annual report, storytelling is a must. You will be put through interview after interview with all these character questions regarding you, and why you want to work for Gartner - must have compelling reason or they won't consider you.
If you want to be sitting in cubicle all day and micromanaged by SMB managers ... good luck!!
