"Business intelligence developers are responsible for developing and maintaining the business data systems of a company. They must be well versed in SQL and other query tools, as well have have strong business analysis to work in tandem with the company's business data. During an interview, be prepared to be tested on these skills by both technical questions and case studies on how you would fix particular problems for a company."
What reporting tools have you used? Actuate, Brio, Crystal Reports? How much experience have you had in scheduling jobs on Unix? Can you write XML and implement it?
The interviewer was interested in breath of experience rather than specific technical skill. Unix work with scheduling and XML skills are necessary, but not heavy (the same procedures are done over and over again). Emphasis was on selling yourself through experience.
