What major challenges and problems did you face in your last position?
No matter how much you enjoy your work, every job involves challenges and issues you need to solve. The interviewer will ask you about these to make sure that you are approaching this position realistically, not afraid of facing a challenge and learn about how you achieve this. Your answer should reflect your ability to overcome challenges and provide an example of how you've done this in the past.
"Overcoming challenges is a key part of an application integration engineer's job. Regardless of how well you plan a project, something unexpected always occurs and needs to be resolved. While I don't look for problems, I enjoy challenges that require me to innovate and be creative to resolve them. For example, I encountered an issue with one of my tools to integrate an application in my last job. It didn't operate properly with the other tools the team was using. After some thought, it occurred to me that there may be a patch available from the vendor. I contacted them and confirmed that they had a solution to this issue. I quickly applied the patch into the tool, and it worked perfectly."
