It is time to flip my answer because the whole matter of weaknesses is more a matter of personal growth. That's life. Being weak at something is a starting point in every life journey. For instance, in a previous job that was presented to me with a large pay increase, in a difficult and somewhat perilous environment of many stakeholders, I began with nothing more than a slate smudged with strained relationships, bad attitudes and angst. It was my job to unravel the underpinnings of relational tensions and get an important project back on course. I began to dig deep into each and every team members’ perspectives on the issues – which indicated the other parties issues were at fault. I’m not a psychologist; still, project technicalities were halting progress so much that relations became as unmanageable as the project.
In short, one day I realized that to resolve every stakeholders' frustrations was futile effort on my part and I had to do something unordinary, unorthodox and unpopular – which I did. I called in the vendor, more precisely, the lab team that invented and patented features of the new technology being ushered into the organization. The plan worked. A Fortune 100 company sent two developers/inventors to the corporate office and I arranged their introduction to my group of high-level tech’s where they sat down and figured things out. Sounds simple but it took one and a half years for me to accomplish this. The complexity was overwhelming.
Go ahead, flip the interview answer: is it weakness to start at the beginning or even half-way point of an issue, struggle through it, move ahead, believe in the change processes which require using one's strength against resistors? Patience.
Nobody rides a bicycle hands-free on the first try. No one hits a homerun the first time at bat. A company may run all the hiring psychometrics to suit their "analytics based" culture but people aren’t science projects: human strength lies in experiencing growth opportunities that will be used to strengthen others.
