Discuss a time you worked with a geographically distributed or culturally diverse work group.

Working with diverse customer bases is a prerequisite for consideration for a Tech Lead at this company. Before your interview, prepare specific examples of the various customer bases you have serviced. If you have no direct experience with diverse work groups, talk about a company that you have worked for that has global reach -- even if you didn't directly support those customers, you should highlight that you have been a part of a company with that type of customer.

This company expects their Tech Leads to be able to collaborate and coordinate with global colleagues across teams.

"My past work for Accenture allowed me to work in a global capacity with teams headquartered in Dublin and across several US and Foreign sites."
