When Heathrow CFO Javier Echave tells us that one of his greatest career lessons was learned from being passed over for the airport’s CFO position, we wonder whether we misunderstood him.  He continues: “It was then that I learned in the most painful way that securing my own succession to the CFO office was dependent on me making myself redundant.”It was a little more than 8 years ago, when a sudden CFO departure, prompted Heathrow's CEO and executive board to appoint one of Echave’s colleagues as “Interim CFO.”For Echave, who had held a succession of senior finance and operations roles, the appointment was an undeniable slight.   “I took it badly,” recalls Echave, who adds that for some time he had perceived himself to be “number two” within Heathrow’s senior finance executive ranks.   According to Echave, after having been passed over, he received some critical advice from the chairman of the airport’s executive board.“He said to me, ‘No one questions your potential and no one questions your strengths, but if you don’t face an interview while believing that you can make a position yours, there’s no chance that you ever will,’” remembers Echave, who notes that he then began to think hard about whether others might see him as having a lack of confidence.Still, given the extant circumstances, the chairman’s insight was not likely to benefit Echave—or so Echave believed, until the interim CFO exited the position within the first 300 days, leaving a second interim CFO opening that Echave then subsequently filled.  Fortunately for Echave, the opportunity allowed him to once and for all address the chairman’s comments.“I determined that my confidence had this Achilles heel, which was that people were questioning it and wondering whether I had become too senior too early,” comments Echave, who reports that ultimately his wife helped him to understand how revealing his passion for the job would better display his self-assurance.“She told me, ’You cannot beg for this—you have to be humble, but you also have to show that you are ambitious as well,’” remarks Echave, who emphasizes the power of ambition.He explains: “This allowed me to bring out my confidence and express why I really wanted the job—and within 6 months, I had it.” –Jack Sweeney
