In late 2012 she "reached out" to her contacts at Microsoft asking them for 30-minute meetings during a trip to Seattle.
Making the move to head office was an eye opener. Whereas there might be two or three people to connect with at Microsoft in New Zealand to complete a project, at "corp" there could be hundreds whose roles had an interest in seeing a particular objective met, says Radovanovich.
Some employees are plucked from the farthest reaches of Microsoft. Bradley Borrows had risen to the top of his field at Microsoft New Zealand. He had won a Microsoft Circle of Excellence award. Only 20 such awards are given out worldwide every year.
He turned down a number of offers to move to the US, but finally took the plunge when he realised he had reached a ceiling in his career in New Zealand.
Paul Andrew was looking for a career move and applied actively for roles in the US. In New Zealand Andrew worked in developer evangelism.
His move to the US pushed him up the ladder and ten years later he is now senior technical product manager of Office 365 in Seattle.
Kiwi Scott Wylie has 20 years Microsoft tenure under his belt and had always had the desire to work at the mothership. "I was working in senior leadership role in the New Zealand subsidiary. There was nowhere to go in terms of my interests and skills.
In January 2013 he boarded a plane for a role as director of developer content in Seattle.
A plan for how to land that job at the global headquarters of an organisation is essential. Look at what you enjoy doing at your subsidiary, says Andrew. "You need to think 'what is my focus area that will get me noticed'."
Sometimes people think they have to get to the top of their discipline to take the leap. That's not the case, says Borrows. There are opportunities at every level - as Radovanovich found out.
Stepping up to roles in the US does require a mind reset. "Don't say: 'back in New Zealand we do it like this'?" which some Kiwis have a tendency to do, says Borrows. "Be ready to embrace change."
